The importance of having a tyre fitted correctly

If your tyres fail the 20p test, then it's time to have them replaced. After all, the contact patch on each tyre is a piece of rubber about the size of your hand, so for optimum safety it pays to have your tyres checked often and fitted correctly when the time comes to change them.
 

When to replace your tyres

If your tyre has suffered damage or there are signs of uneven tread wear, then the tyre needs to be replaced. You’ll also need to check the age of your tyres by reading the information on the wall of the tyre and looking for signs like crazing in the rubber and a distorted tread. This is particularly important if you're thinking of fitting tyres that have been kept in storage to your vehicle. Find out if your tyres are due for a change by reading our guide here.
 

Picking the right tyres for the job

Aim to replace your tyres in pairs across the axle, or all four at the same time. At Protyre we have a tyre selector that will suggest alternatives to your original tyres when you plug in the information on size, load rating and speed rating (all of which is stamped on the sidewall of your car tyre).
 
There’s no legal obligation to stick with the original tyres for your vehicle but they should be of the tread pattern and size best suited for your make and model of car. However, it is illegal to mix tyre sizes and construction types (radial, cross ply) across an axle.
 
If you only intend to replace two tyres, make sure they’re as close a match as possible to the existing tyres and are fitted to the back axle. This will ensure that the handling of your car is as stable as possible.


Check the fitting

It can’t be overstated that any time you change your tyres, they need to be correctly fitted. This will keep your vehicle safe and roadworthy. If you choose asymmetric or directional tyres, then they must be fitted according to the markings on the tyre sidewall or you won’t benefit from the innovative design and they can become dangerous.
 
Asymmetrical tyres will have an inside and outside face, which is clearly marked. Directional tyres have an arrow marking the direction of rotation. If the inside face is mounted outwards or the arrow is pointing in the wrong direction, ask your tyre fitter to correct the mistake. Failure to have these types of tyres fitted in the correct way will lead to an MOT failure.
 

Running in your tyres

After fitting, you’ll need to keep an eye on your locking wheel nuts and check for any signs of loosening after the first 50 miles, and regularly after that. Check your tyre pressure once a fortnight and be aware of any steering adjustments. Although your tyres should be precisely balanced after fitting, if you experience any vibration - particularly when travelling at speeds between 65-70mph - then readjustments will need to made.
