Tyres that are carefully maintained will last longer than those that are neglected. There are some avoidable factors that affect tyre life, for which you can depend on the expert advice of your dealer.
Correct inflation pressures are undoubtedly a major consideration in obtaining the best performance and life from tyres. Deviation from the manufacturer's recommendations may lead to distinct deterioration in performance as well as tyre life.
When running normally, tyres get hot. The air inside tries to expand, and since it is unable to do so, the pressure increases. Tyres are designed to accommodate such rises in temperature. Do not attempt to 'bleed' the air from the hot tyre to reduce the pressure to cold starting pressures. This simply under-inflates the tyre, which leads to undue heat generation and can be dangerous.
Incorrect maintenance, particularly under-inflation, may result in serious tyre damage.
Replacement of tyres
Determine the following:
Original equipment size. Check the tyre placard in the vehicle or the vehicle owner's manual for the tyre size recommended by the vehicle manufacturer.
Recommended tyre inflation pressure. This information can be found along with the tyre size.
Rim size. Check the size of the rim on which you will mount the replacement tyre. If the size has not been stamped on, the rim should be measured.
The tyre fitted as original equipment to a vehicle has been determined by the vehicle manufacturer in conjunction with the tyre manufacturer, taking all operating factors into account. A change in size, construction or load and speed rating should only be considered after consulting a tyre professional such as your dealer.
