Warning
Do not mix different types of tyres on the same vehicle such as radial, bias or bias belted tyres except in emergencies (temporary spare usage).

Warning
Never run the engine with one wheel off the ground, for example when changing a wheel. The wheel resting on the ground may cause the vehicle to move.

Warning
After market aerosol tyre sealants are extremely flammable. Always question the customer to make sure these products have not been used.

Warning
Always wear safety goggles or a face shield when performing any work with wheel and tyre assemblies.

Warning
Check road wheel nuts torque at 32 km (20 miles) after any wheel change or any time the wheel nuts are loosened.

Warning
When changing a wheel, make sure that the vehicle cannot move. Always apply the parking brake and select the transmission park position (Automatic transmission only).

Warning
Reduce air pressure as much as possible by pushing the valve core plunger in before removing the valve core.

Warning
Each individual axle, road wheel and tyre has its own maximum weight or tyre inflation rating. Do not overload or over-inflate beyond the capacity of the lowest rated components of the system.

Caution
Do not clean the aluminium alloy wheels with steel wool, abrasive type cleaners or detergents. Failure to follow these instructions may result in damage to the vehicle.

Caution
Paraffin (kerosene) must not be used as a cleansing agent on tyres.

Tyre Pressures

Tyre pressures must be checked with the tyres cold.

Warning
PDI Inspection.
Tyre pressures must be reduced to normal level during PDI. The vehicle must never be run on road with elevated tyre pressures, driveability may be seriously compromised.

Caution
In order to protect tyres against flat spots during storage and transportation, tyre pressures should be increased to 65 - 70 psi (450 - 500 kPa). Ensure that the tyre pressure are set to the recommended tyre pressures before driving.
