loosened. Failure to follow these instructions may result in personal injury.

WARNING: Failure to retighten the wheel nuts at the specified mileage could cause the wheels to come become

detached while the vehicle is in motion. Failure to follow these instructions may result in personal injury.

WARNING: Each individual axle, wheel and tire has its own maximum weight or tire inflation rating. Do not

overload or over-inflate beyond the capacity of the lowest rated components of the system. Failure to follow these
instructions may result in personal injury.

WARNING: When changing a wheel, make sure that the vehicle cannot move. Always apply the parking brake and

select the transmission park position. Failure to follow these instructions may result in personal injury.

WARNING: Reduce air pressure as much as possible by pushing the valve core plunger in before removing the

valve core. Failure to follow these instructions may result in personal injury.

CAUTION: Do not clean aluminium wheels with steel wool, abrasive type cleaners or detergents. Failure to follow

these instructions may result in damage to the vehicle.

CAUTION: The vehicle is fitted with directional tires, which should always be fitted in accordance with the

direction of rotation symbol on the tire.

NOTE:

The maximum distance that can be driven on a punctured tire varies greatly depending on the type of terrain.

The vehicle is only available with 19 inch wheels, due to the specification of the brakes and tires fitted. The
vehicle is fitted with 255/45 ZR19 104Y Pirelli P Zero, which feature a run-flat capability. For additional

Wheels and Tires - VIN Range: G00442-

General notes

Factory installed tires and wheels are designed to operate satisfactory when inflated to the

recommended inflation pressures; refer to the Specifications sub-section. The recommended

pressures apply to vehicle loads up to and including full-rated load capacity.

Correct tire pressures and driving technique have an important influence on tire life. Heavy

cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear.

Replacement tires should follow the recommended:

•

size.

•

speed rating.

•

load range.

•

radial construction type.

The use of any other size or type may seriously affect:

•

safety.

•

ride.

•

handling.

•

speedometer and odometer calibration.

•

vehicle ground clearance.

•

tire clearance between body and chassis.

•

wheel bearing life.

•

brake cooling.

Wheels need to be renewed when:

•

impact damaged.

•

heavily corroded.

•

porous.

•

wheel stud holes or seats become damaged.

•

they have excessive radial or lateral runout.

Safety notes

WARNING: Do not mix different types of tires on the same vehicle. Handling may be

seriously affected resulting in loss of control. Failure to follow these instructions may result in
