WHEN SHOULD I CHANGE MY TYRES?
Tyres are one of the most important and most overlooked parts on a vehicle.They are of course the main point of contact in which your vehicle has with the road, and many people fail to realise that tyres require maintenance to make sure they work to the best of their best ability.
We want to provide you with some useful tips, allowing you to avoid common damage to your tyres. If you return your lease with any of the following you will incur charges which can be sizeable.
Cuts – Cuts are relatively common and can occur as a result of driving over sharp objects on the road. In UK law, a tyre with a cut in excess of 25mm must be replaced. Any cut that exposes the ply or cord is also illegal – in both cases, there is an increased risk of blowout.
Sidewall impact – Hitting a curb or another obstacle can sometimes cause damage to the casing, either in the form of a cut or bulge. Again, these are a blowout risk.
Camber wear – In suspension terms, ‘camber’ refers to the angling of wheels away from the axle. Some set-ups can improve handling, however, tilting wheels in this way tends to cause rapid wear on the edge of the wheel that makes contact with the road.
Under-inflation – Under-inflation causes the outer edges to take the load and thus wear more quickly than the centre.
Over-inflation – When filled with too much air, a tyre becomes too rounded, causing the middle to extrude and take the entire weight of the car.
Emergency braking – At high speed, an emergency stop can cause massive friction resulting in rapid wear, potentially to the extent that the tyre punctures and deflates. For this reason, you should always check your tyres at the nearest safe opportunity after performing an emergency stop.
Misalignment – Whereas camber configuration may be desirable, plain old misalignment (where the front wheels are pointed at slightly different angles) rarely results in a better drive and can cause some rapid wear and feathering on the tread.
