Never use a tyre over Six Years old, regardless of whether it has been used or not. Incorrect tyre pressure may adversely affect tyre life and vehicle handling. Tyre pressure should be checked when tyres are Cold after the vehicle has been parked for three or more hours, or driven less than 1 mile. COLD tyre pressures are shown on garage forecourt. Different vehicles have different tyre pressures so check the charts.
Insufficient pressure can lead to overheating of the tyre and subsequently internal damage.
At high speeds, this could result in tread separation and even bursting of the tyre. Tyres should also be inspected for wear, cracking, bulging, or objects caught in the tread. If excessive wear, cracks, bulging, or deep cuts are found, the tyre should be replaced. When wear indicator is visible, the tyre should be replaced. Cars, light vans and light trailers must have a tread depth of at least 1.6mm across the central three-quarters of the breath of the tread and around the entire circumference.
