Operation Tires and wheels Life of tires The service life of a tire is dependent upon various factors including but not limited to: Driving style Tire pressure Distance driven Warning! Direction of rotation Unidirectional tires offer added advantages, such as better aquaplaning performance. To benefit, however, you must ensure that the tires rotate in the direction specified. An arrow on the sidewall indicates the intended direction of rotation of the tire. If the tires are warm you should only correct the tire pressure if it is too low for current operating conditions. A table on the fuel filler flap lists the specified tire inflation pressures for warm and cold tires as well as for various operating conditions. i The pressures listed for light loads are minimum values offering high driving comfort. G Checking tire inflation pressure Warning! If the tire pressure repeatedly drops check the tires for punctures from foreign objects check to see whether air is leaking from the valves or from around the rim Tires and spare tire should be replaced after six years, independently of the remaining tread. G ! Keep unmounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease and gasoline. Increased inflation pressures listed for heavier loads may also be used for light loads. These higher pressures produce favorable handling characteristics. The ride of the vehicle, however, will be somewhat harder. Never exceed the maximum values or inflate tires below the minimum values listed in the fuel filler flap. Correct the tire pressure only when tires are cold. 235
