Do all 4 tyres need to be the same speed rating?

For optimal safety and performance, we recommend fitting the same tyres to every wheel position on your car, so you should have the same brand, size, tread pattern, load index and speed rating on the front and rear tyres.

Should all 4 tires have same speed rating?

Just remember, never mix and match tires with different speed ratings on your vehicle. This will cause major problems with the handling of your vehicle. If tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle, regardless of which axle is driven.

Does it matter if my tyres have different speed ratings?

A tyre with a higher speed rating will give better grip and stopping power but may not last as long and may not perform as well in cold weather/winter conditions. V, Z, W, and Y-rated tyres, therefore, tend to be better suited to high-performance vehicles driven in warmer climates.

Can I fit tyres with a lower speed rating?

It is important to check your vehicle handbook and ensure that any new tyres match, or even exceed, your car's maximum speed. You should never fit a tyre with a lower speed rating than was originally fitted to your vehicle during production.

Do all 4 tyres need to be the same?

It is perfectly legal to use different brand tyres on your car, however, this doesn't always mean you should. Slight differences in the tyre could end up causing huge differences in performance, which can ultimately end up damaging both your car and your wallet as a result!

Which is better? Race or Track Tires in Need for Speed Heat | I Tested both on 10 different cars!

Is it OK to have mismatched tires?

A car with mismatched front and back tires should still be usable, especially if it is a two wheel drive vehicle. Tires wear out at different rates, and if one is more worn than the other, simply rotating the tires may be a possibility to prevent further wear.

Can I have 4 different tyres on my car?

Primarily, you should avoid mixing different tyre brands and different tread patterns. There are rare exceptions for approved mixed-tyre fittings, but in general, manufacturers do not recommend tyre mixing at all.

Can you have different tyres on front and back?

Can you have different size tyres front and back? Generally, in a front or rear-wheel drive, as long as you have ensured both pairs of tyres are the same, you can have different size tyres between rear and front if the suspension geometry is set to accommodate for this.

Can you mix W and Y rated tyres?

Mixing tyre speed ratings isn't recommended. If you are in a situation where you must mix tyre speed ratings (after an emergency puncture, for example) then make sure the lower-rated tyres are on the front axle to prevent turning more sharply than you intended (oversteering).

Can I use a tyre with a higher load rating?

Is it possible to fit tyres with a higher load index and a lower speed rating than my manufacturer recommends? Yes, you can fit tyres that have a higher load index and a lower speed rating.

Can you put H-rated tires instead of V?

A V-rated car requires a tire designed to operate to a maximum of 149 mph and can thus not be fitted with an H-rated tire.

Can I use T rated tires instead of H?

A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.

What's the difference between Y and W on tyres?

Z-rated high-performance tyres are rated for speeds in excess of 149mph. Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph. Y-rated tyres are rated in excess of 186mph.

Do tyres have to match for mot?

Car tyres and the MOT

It's not illegal to have tyres from different manufacturers fitted to your car. However, you will fail the MOT if you have tyres of two different sizes fitted across the same axle.

Is it OK to have 2 different brand tires?

We recommend that the same tyres are fitted on all wheel positions of your vehicle. If however, due to availability or economical considerations, mixing is necessary then it is permissible to mix brands and tread patterns as long as the same tread patterns and brands are fitted across the same axle.

Are remould tyres legal in UK?

Remoulds are still legal in the UK, as long as they comply with strict regulations, and if manufactured with care they needn't be significantly less safe than new tyres.

Do I need to change both front tyres at the same time?

Because tyres are the only point of contact between your car and the road, having two different tyres on the same axle is not advised. Pairing an old tyre with a new one will cause an imbalance in rolling resistance and grip, causing unpredictable performance, steering problems and using more fuel.

Can I replace only 1 tire?

Typically, when you're faced with replacing only one tire, it's the result of an unrepairable situation such as a flat or a blow-out. Unfortunately, not all tires are repairable or worth saving. Replacing only one tire mostly depends on how much tread is remaining on the opposite tire on the same axle.

What does Z mean on tyres?

SPEED RATING Z

A “Z” rating can mean different things. While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire's size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph).

Do higher speed rated tires wear faster?

They're also about ride comfort, wear and cornering ability. Typically, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.

What does H mean on tyres?

Speed rating

Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).

Why do tyres have 2 load ratings?

Expressed as a two or three digit number, the load index tells you what the maximum allowed weight your tyre can carry. Some tyres have a dual rating, for example “96/94N”, where the 96/94 is the load index. Whenever there are two numbers shown like this, this is for multiple-axle applications.

Can you mix XL tyres with normal tyres?

Don't mix different load rated tyres on the same axle.

What are three legal requirements relating to TYRE tread?

The legal minimum tyre tread depth varies by each type of vehicle. At least 1.6mm throughout a continuous band in the centre 3/4 of the tread and around the entire circumference of the tyre. At least 1.0mm throughout a continuous band across at least 3/4 of the breadth of the tread and around the entire circumference.

What is classed as an illegal tyre?

To help you judge how much tread you have on your car tyres, manufacturers often mould tread bars at roughly 1.6mm. If you can see these bars your tyres are about to become illegal and unsafe. However, for optimum safety, most manufacturers recommend that your tyres are changed at 3mm.
