Worn tires cause reduced performance. It takes longer to brake on a wet road surface when tires are worn, and there is more risk of skidding. Underinflated tires reduce your control of the vehicle, increase braking distances and wear out your tires more rapidly. Over-inflated tires reduce grip, reduce stability in braking and lead to poor handling.
You should inspect your tires at least once a month. The correct pressure information can usually be found on the edge of the driver’s side door. Check your tires for signs of damage or cracks. Even a small tear should be checked by a tire technician. All tires have tread wear indicators. These indicators appear in the main grooves when the tread has worn down to 1.6mm, showing the tire needs to be replaced.
