All tyre topics

Choosing tyres

Summer, winter or all-season tyres?

Start with the journeys you cannot postpone, rather than the first discounted set you find.

Choosing tyres

Tyres for low annual mileage

Low mileage can preserve tread, but it does not settle every tyre choice.

Choosing tyres

Choosing tyres for frequent motorway trips

Long journeys call for attention to wet performance, loading and the approved specification.

Choosing tyres

Tyres for city driving and short journeys

Short trips involve repeated starts, tight turns and frequent proximity to kerbs.

Choosing tyres

Choosing tyres for an electric car

For an electric car, establish the vehicle requirements before comparing range and noise.

Choosing tyres

Choosing tyres for a heavy SUV

Axle loads and the approved tyre specification matter more than an SUV badge.

Choosing tyres

Tyres for a family estate car

For an estate car, everyday journeys and a fully loaded holiday both belong in the decision.

Choosing tyres

Choosing tyres for a small car

A smaller size does not make technical specifications or wet-road results less important.

Choosing tyres

Van tyres: establish use and load first

Specify van tyres from the vehicle approval and loading requirements, rather than tread appearance.

Choosing tyres

Choosing motorhome tyres

Body type, axle loads and long periods parked make motorhome tyre selection a separate task.

Choosing tyres

Checking tyres for a caravan

On a caravan, age and loading may deserve more attention than the amount of tread still visible.

Choosing tyres

Trailer tyres: more than dimensions

A trailer needs a compatible combination of load capacity, speed specification and wheel.

Choosing tyres

How to weigh wet grip when buying tyres

Wet grip can be compared, but no single figure describes every rain-soaked road.

Choosing tyres

Quiet tyres: what the figures tell you

External rolling noise and the sound inside the cabin are different measurements.

Choosing tyres

Understanding rolling resistance and consumption

Lower rolling resistance can help consumption, but actual savings depend on more than a label.

Choosing tyres

Considering tyres and ride comfort together

Ride quality comes from the tyre, wheel, pressure and vehicle together, not one advertising phrase.

Choosing tyres

Considering performance tyres for everyday driving

A performance tyre should suit daily conditions as well as the car’s power.

Choosing tyres

Comparing budget and premium tyres

Compare specific models and total costs rather than two broad price categories.

Choosing tyres

Tyre tests: does the tested size match?

A test result belongs to a specific size and version, not automatically every variant.

Choosing tyres

Reading tyre tests around your own needs

Overall grades make more sense when read alongside the conditions and individual criteria.

Choosing tyres

New tyre model or established range?

A new model name brings a change, but not automatically comparison data in your size.

Choosing tyres

Assessing used tyres before buying

With used tyres, their history remains an essential part of the assessment.

Choosing tyres

Understanding retreaded passenger-car tyres

Retreading reuses an existing casing through a production process; it is not simply resale of an old tyre.

Choosing tyres

Run-flat tyres: requirements before purchase

Run-flat capability belongs to a compatible vehicle system, rather than being a universal puncture solution.

Choosing tyres

Understanding self-sealing tyres

A sealing layer can address certain penetrations, but does not replace damage assessment.

Choosing tyres

Tyres with acoustic foam

Acoustic foam addresses sound inside a tyre; it is not a puncture-sealing layer.

Choosing tyres

Vehicle approvals and OE tyre markings

OE markings identify particular original-equipment versions; their meaning depends on manufacturer and vehicle.

Choosing tyres

Different tyre models on one car

Different tyres need assessment as a combination, not merely as four individually matching sizes.

Choosing tyres

Replace two tyres or all four?

Remaining condition and vehicle requirements matter when replacing less than a full set.

Sizes & markings

Reading 205/55 R16 91V

The sequence combines dimensions, construction and service ratings. Keep it complete when buying.

Sizes & markings

What tyre width describes

The first number describes nominal section width, not simply the visible tread.

Sizes & markings

Aspect ratio: why 55 is not millimetres

An aspect ratio becomes a calculated height only when combined with width.

Sizes & markings

Matching tyre and rim diameter

Tyre diameter must match the wheel exactly; similar numbers do not provide fitting flexibility.

Sizes & markings

The R in a tyre size

Within the size marking, R means radial construction rather than radius or width.

Sizes & markings

Understanding the load index

The number after the size is a table code, not a weight written directly in kilograms.

Sizes & markings

Speed rating and vehicle approval

A speed rating describes technical capability, not the permitted speed on a road.

Sizes & markings

XL tyres and their load capacity

XL identifies an increased load version within a size, not extra permitted vehicle payload.

Sizes & markings

What HL means on a tyre

HL identifies a particular higher-load requirement and is not freely interchangeable with XL.

Sizes & markings

Distinguishing C and CP tyres

C and CP identify different applications; vehicle documents determine the appropriate replacement.

Sizes & markings

Finding a tyre manufacture date

Four digits identify production week and year, but not the complete service history.

Sizes & markings

Recognising the Alpine symbol

The mountain-and-snowflake symbol is a defined marking, not generic winter artwork.

Sizes & markings

M+S is not the same as Alpine

M+S lettering and the Alpine symbol do not carry identical meaning.

Sizes & markings

Following the rotation arrow

The sidewall arrow identifies the intended rotation when travelling forwards.

Sizes & markings

Inside and Outside when fitting tyres

On asymmetric tyres, the marking identifies the sidewall intended to face outwards.

Sizes & markings

Finding TWI marks and wear bars

TWI marks help locate tread-wear indicators, but do not replace a complete condition check.

Sizes & markings

Understanding the E approval mark

An approval marking is neither a manufacturing-origin statement nor a tyre-quality ranking.

Sizes & markings

Tubeless tyres and tube-type tyres

Tubeless means operation without a separate inner tube, not immunity to pressure loss.

Sizes & markings

Maximum pressure is not the vehicle target

The sidewall maximum is not your vehicle’s routine inflation target.

Sizes & markings

Max Load on the tyre sidewall

Max Load describes a tyre capacity under conditions, not the car’s payload allowance.

Sizes & markings

Reading the EU tyre label

The label brings together several comparable properties, but is not a complete tyre assessment.

Sizes & markings

QR codes and EPREL when buying tyres

The QR code leads to a product record; the key question is whether it matches the offered version.

Sizes & markings

Decibels and noise classes on the label

The noise figure describes rolling sound outside the car. It is only part of the picture when you want a quiet cabin.

Sizes & markings

Snow and ice symbols on the tyre label

The two winter pictograms refer to different tests. An ice symbol is not a universal upgrade for every winter tyre.

Sizes & markings

Tyre sizes in vehicle documents

The registration document is the starting point. Additional approved combinations may appear in other vehicle-specific paperwork.

Sizes & markings

Finding additional sizes in the CoC

The CoC may contain additional wheel-and-tyre combinations. It must match the vehicle variant and be read as a complete document.

Sizes & markings

Calculating rolling circumference: the limits

Geometry can explain differences between sizes. It cannot replace approval or checks on the vehicle.

Care & checks

Checking tyre pressure when cold

Measure before driving so that heat does not distort the comparison. The target still comes from the instructions for your own vehicle.

Care & checks

Reading the vehicle pressure placard

Several numbers on one sticker are not contradictory. They may belong to different axles, sizes or loading conditions.

Care & checks

Tyre pressure with a full load

Passengers and luggage change the operating conditions. Use the vehicle manufacturer’s load-related pressure information.

Care & checks

Do not deflate hot tyres to cold targets

A higher reading after driving can result from heat. Do not simply use a cold-pressure figure as a target for releasing air.

Care & checks

Recognising slow pressure loss

Repeated topping-up is a clue, not a repair. Comparable readings help a specialist investigate the cause of a leak.

Care & checks

Checking valves and valve caps

The small cap protects an important opening. If air escapes, the complete valve needs attention.

Care & checks

Choosing a tyre-pressure gauge

Readable units, a usable connector and verifiable accuracy matter more than extra decimal places.

Care & checks

Understanding direct TPMS

Wheel-mounted sensors provide pressure information. A second wheel set needs compatible hardware and the correct setup procedure.

Care & checks

Understanding indirect TPMS

An indirect system analyses existing vehicle signals. It needs correctly inflated tyres before a reference is stored.

Care & checks

When a tyre-pressure warning appears

A warning calls for attention to the tyres first. Resetting the display is not the starting point.

Care & checks

Resetting TPMS after checking pressures

Store a new reference only after checking the tyres and setting their specified pressures.

Care & checks

Measuring tread depth in several places

One reading can miss local wear. Measure several positions around the circumference and across the tread.

Care & checks

Recording uneven tyre wear

A wear pattern is a clue, not a certain remote diagnosis. Clear records make professional investigation easier.

Care & checks

Wear on the inner tyre shoulder

The shoulder facing the car is easy to miss during a quick walk-around. Wear there calls for a complete inspection.

Care & checks

Recognising sawtooth tyre wear

Different heights at the edges of tread blocks can create rolling noise. Inspection must distinguish the pattern from its possible causes.

Care & checks

Flat spots after extended parking

Tyres may initially feel uneven after extended parking. Strong or persistent vibration must not be assumed harmless.

Care & checks

Having sidewall cracks assessed

Age and tread depth alone cannot assess cracks. The affected area and the complete tyre need examination.

Care & checks

A bulge in a tyre sidewall

An outward bulge can indicate damage to the load-carrying structure. Stop using the tyre and do not attempt a home repair.

Care & checks

A nail or screw in a tyre

Do not pull an embedded object out as a test. Repair suitability can only be decided after a complete examination.

Care & checks

Checks after a kerb impact

A visible scrape does not tell the whole story of an impact. Tyre, wheel and suspension can be affected differently.

Care & checks

Tyre checks after a pothole

Damage after a hard impact can be hidden inside. Looking only at the outer rim edge cannot establish condition.

Care & checks

New vibration after a tyre change

New vibration after fitting needs prompt investigation. Balancing is one possible remedy, not a diagnosis for every case.

Care & checks

Cleaning tyres without damaging them

Water, a suitable mild cleaner and careful handling are usually enough. Shine is not a measure of tyre condition.

Care & checks

Storing complete wheels

A mounted tyre is supported by its wheel. Storage hardware, room conditions and preparation must suit the complete set.

Care & checks

Storing tyres without rims

An unmounted tyre has no rigid wheel supporting it. Protect its shape and bead area during storage.

Care & checks

Choosing a place to store tyres

Not every empty garage or basement corner is suitable. Consider conditions throughout the entire storage period.

Care & checks

Recording tyre position and condition before storage

A short record for each wheel prevents mix-ups and identifies issues that need resolving before the next fitting.

Care & checks

Assessing tyre age together with condition

The production date matters, but it cannot certify condition by itself. Low mileage does not prevent ageing.

Care & checks

Rotating tyres according to vehicle instructions

Changing positions can distribute wear. The permitted pattern depends on the vehicle, wheel combination and tyre construction.

Care & checks

Including the spare wheel in tyre checks

An unused spare can still lose pressure and age. Include it in maintenance before it is needed.

Care & checks

Checking a tyre set after storage

A stored set needs a fresh assessment before fitting. Old readings and a clean cover are not sufficient.

Wheels & fitting

Comparing steel and alloy wheels

Material, finish and the particular wheel version are separate decisions. Compare complete options approved for your car.

Wheels & fitting

Rim width and tyre approval

The first number in a wheel size and the first number in a tyre size describe different widths. They need to work together.

Wheels & fitting

Understanding wheel offset

Offset describes the mounting face relative to the wheel centreline. A different number can move the wheel without changing its width.

Wheels & fitting

Checking bolt pattern and bolt count

Five fixing holes do not make two wheels interchangeable. The diameter of their bolt circle is part of the specification.

Wheels & fitting

Centre bores and centring rings

A centring ring is a specified component, not a universal remedy for an unsuitable wheel.

Wheels & fitting

Checking wheel load capacity

Wheel load capacity applies to the wheel; load index applies to the tyre. A suitable combination must satisfy both.

Wheels & fitting

Reading wheel approval documents

Finding the model name is only the beginning. Wheel version, tyre combination and conditions determine what the document means for your car.

Wheels & fitting

Brake clearance before buying wheels

A matching nominal diameter does not guarantee caliper clearance. Check the exact wheel shape against the actual brake package.

Wheels & fitting

Different wheel sizes front and rear

With staggered fitment, front and rear are selected as one matched combination rather than independently.

Wheels & fitting

Larger wheels: what changes

A larger wheel changes more than appearance. Assess and approve the complete wheel-and-tyre combination.

Wheels & fitting

Smaller winter wheels need approval

A smaller winter wheel set may be an approved option. Brake equipment and application conditions determine whether it suits the car.

Wheels & fitting

Wheel bolts must match the wheel

Thread, seat and length form one specification. A bolt head that accepts the socket is not enough.

Wheels & fitting

Keeping locking wheel bolts and their key

The matching adapter needs to be available when required. Its reference and allocation help if it is lost or damaged.

Wheels & fitting

Finding the correct wheel-tightening torque

The correct torque belongs to a particular connection and its fitting conditions. A commonly quoted internet value is not universal.

Wheels & fitting

What wheel balancing involves

Balancing corrects mass distribution around a wheel. It does not replace damage inspection or wheel alignment.

Wheels & fitting

Wheel alignment and tyre wear

An uneven wear pattern deserves investigation. Alignment provides measurements, but it does not automatically explain every symptom.

Wheels & fitting

Distinguishing tyre fitting from wheel changing

Changing a complete set of wheels differs from fitting tyres onto existing rims. The distinction determines what you need to book.

Wheels & fitting

Planning for TPMS when buying wheels

An additional wheel set must work with the car's tyre-pressure monitoring system. Establishing that before ordering avoids an incomplete purchase.

Wheels & fitting

Having wheel corrosion checked

Brown marks, flaking paint and pressure loss are different observations. Establish whether the issue affects appearance alone or an important wheel function.

Wheels & fitting

Suspecting a bent wheel

A pothole impact can damage a wheel without leaving an obvious large crack. Changed behaviour afterwards deserves investigation.

Wheels & fitting

Cleaning wheels without aggressive products

Wheel cleaning should remove dirt without unnecessarily stressing the finish or neighbouring components. Start by identifying the wheel surface.

Wheels & fitting

Protecting wheels during transport and storage

A wheel set should survive its time off the car without acquiring fresh damage. Transport, condition and storage arrangements all play a part.

Wheels & fitting

Do not choose wheel spacers without checks

Wheel spacers change where a wheel sits on the vehicle. Matching the number of bolt holes is therefore only a small part of choosing them.

Wheels & fitting

Collecting a car after wheel fitting

Collection is a good moment to compare the order, the fitted wheels and the invoice. Questions are easiest to resolve while the car is still at the workshop.

Weather & journeys

Winter-tyre requirements in Germany

Germany's winter-tyre requirement follows road conditions. A fixed changeover date or an M+S marking alone does not settle the question.

Weather & journeys

Planning tyre changes beyond a calendar date

A calendar helps reserve an appointment. Weather, driving patterns and the condition of your tyre sets determine whether the timing suits you.

Weather & journeys

Putting the seven-degree rule in context

Seven degrees is a familiar reminder for seasonal tyre changes. It is neither a legal trigger nor a universal performance boundary.

Weather & journeys

All-season tyres for your winter conditions

Whether all-season tyres suit your winter depends on more than your home address. Consider the routes you genuinely need to drive.

Weather & journeys

Checking tyres before an Alpine trip

An Alpine journey often crosses countries, altitude bands and changing weather. Check tyres and additional equipment against the whole route.

Weather & journeys

Checking snow chains and tyre size together

Tyre size is essential when choosing snow chains, but it is not the only information. Vehicle approval, chain design and fitting instructions must agree.

Weather & journeys

Clearance when using snow chains

Chains need adequate space between the tyre and surrounding vehicle parts. Looking at a stationary car does not establish that clearance.

Weather & journeys

Checking winter equipment before driving abroad

An international trip involves more than the destination. Transit countries and last-minute route changes may bring different winter-equipment requirements.

Weather & journeys

Tyre checks before a summer holiday

A long summer journey often changes more than the route: the car carries more weight, runs for longer periods and may use unfamiliar roads.

Weather & journeys

Planning luggage load with tyres in mind

Additional luggage changes vehicle loading. Tyre pressure and load capacity therefore belong in packing plans, not only in the final fuel stop.

Weather & journeys

Tyres before a journey with a trailer

A towing journey needs a tyre check covering both car and trailer. Wheels on a rarely used trailer deserve particular attention.

Weather & journeys

Tyres in heavy rain

In heavy rain, tyres must displace water while transmitting forces. Their condition matters, but it does not replace adapting the journey to the weather.

Weather & journeys

Aquaplaning: the limits of tyre grip

Aquaplaning is more than a slippery surface. Water can reduce contact between tyre and road so substantially that steering and braking forces are no longer transmitted as expected.

Weather & journeys

Checking tyres during hot weather

Hot weather changes pressure readings and can add demands to a journey. The correct vehicle specification under appropriate measuring conditions remains the reference.

Weather & journeys

Why tyre pressure falls in cold weather

A substantial fall in ambient temperature can lower tyre pressure. That seasonal effect does not automatically explain every loss of air.

Weather & journeys

Tyres when a car is parked for a long period

A car returning from a long period off the road needs a fresh condition check. Low mileage does not mean the tyres have remained unchanged.

Weather & journeys

Keeping winter tyres on in summer?

Using up an existing winter set through summer can look tempting. The decision should involve more than the cost of the next changeover appointment.

Weather & journeys

Tyres and loads before mountain roads

Before mountain roads, consider tyres, vehicle load and the route together. There is no universal mountain-pressure adjustment that replaces those checks.

Weather & journeys

Tyre checks after gravel roads

Gravel can bring small stones and concealed edges. After such a road, a calm check in a safe location can help identify changes.

Weather & journeys

Inspecting rental-car tyres before departure

A rental car arrives with tyres already fitted. Looking before departure helps raise obvious defects and equipment questions while they can still be resolved.

Weather & journeys

Checking a puncture kit before a journey

A puncture kit is available only if it is complete, usable and accessible. Check it before travelling rather than beside a damaged tyre.

Weather & journeys

Finding a safe stopping place after tyre trouble

With suspected tyre damage, reaching a safe stop comes before diagnosis. The next step depends on traffic, location and vehicle condition.

Buying & workshops

Comparing complete tyre quotations

A low unit price does not tell you what four fitted tyres will cost. Put each quotation on the same basis.

Buying & workshops

Ordering tyres online: matching the details

An online tyre order needs agreement between vehicle approval, product specification and the service offered. The cheapest result becomes comparable only after those checks.

Buying & workshops

Checking a tyre delivery

Inspect new tyres before fitting. A clearly documented discrepancy is easier to resolve while the goods have not yet been used on the vehicle.

Buying & workshops

Discussing manufacture dates when buying new tyres

Manufacture date is one piece of information when buying tyres. Discuss expectations before ordering and consider date, storage and condition separately.

Buying & workshops

What a fitting quotation should include

A fitting price is comparable only when the included work is clear. Ask about the completed job on the car, rather than one isolated line item.

Buying & workshops

Tyre storage services: clarify what is included

A tyre-storage service takes care of a set between uses. Establish which additional tasks are included before handing it over.

Buying & workshops

Preparing for a tyre workshop appointment

Preparing a workshop appointment reduces questions at the car. A precise job description, suitable documents and a way to authorise decisions matter most.

Buying & workshops

When a tyre needs a repair assessment

A photograph cannot reliably establish whether a damaged tyre can be repaired. Assessment must consider the injury, its history and the applicable manufacturer requirements.

Buying & workshops

Puncture sealant and subsequent repair

After using puncture sealant, arrange workshop assessment. Explain which product was applied and what happened after the puncture.

Buying & workshops

Using a temporary spare within its limits

A temporary spare has its own operating restrictions. It is an interim solution, not another ordinary tyre in the fitted set.

Buying & workshops

A puncture with run-flat tyres

Run-flat technology may provide limited mobility after pressure loss. The permitted use depends on the particular tyre and vehicle.

Buying & workshops

Taking old tyres to an authorised collection point

Old tyres belong in an organised disposal route. Establish acceptance conditions and charges before loading them or leaving them outside a business.

Buying & workshops

Keeping tyre invoices and product details

A tyre invoice is more useful later when it identifies the exact specification and vehicle. Organise the records after purchase and fitting.

Buying & workshops

Documenting a tyre complaint

A complaint is easier to assess when the observation, product and timeline are clear. Document facts and resolve safety-related questions first.

Buying & workshops

Reading tyre warranty promises

A warranty promise may add benefits. Read who provides it, what it covers and the conditions attached.

Buying & workshops

Assessing a used complete wheel set

Four used wheels are four separate items to assess. Matching dimensions and a tidy appearance are not enough.

Buying & workshops

Checking tyres when collecting a car

At vehicle collection, the tyres actually supplied should match the agreement. Include any additional wheel sets that form part of the purchase.

Buying & workshops

Comparing annual tyre costs

One year-round set removes some changeover costs. Its overall cost also depends on use, replacement timing and the wheels you already own.

Buying & workshops

Questions to ask before a tyre-workshop visit

Vehicle details and a few focused questions help establish what the workshop needs to assess and quote for.

Buying & workshops

Keeping a useful tyre-replacement record

A short record connects the invoice, tyre set and vehicle. It is easier to use later than a folder full of unidentified photographs.
