* Warning

Vehicles equipped with aluminum wheels need to be maintained to proper lug torque.

Upon initial installation, lug nuts must be torqued. After the first 50 miles, lug nuts must

be retorqued per the torque specification chart. This procedure must be repeated

whenever the wheel is removed from the vehicle.

Load Ratings of WheelsLoad Ratings of Wheels

Wheel load ratings are based on the vehicle weight that each wheel is capable of

safely carrying.

Because of the cargo carrying design of pickups and utility vehicles, they are subject to

greater loads on the rear wheels than passenger cars. Caution must be taken to insure

that the total rear axle load (cargo + vehicle) does not exceed the load rating of the

wheels. Caution must also be taken to insure that the maximum tire diameter is not ex-

ceeded.

* Warning

Do not exceed the maximum tire diameter as stated on the load-rating label.

* Warning

Do not exceed 40 PSI when seating the tire to the bead of the rim.

Balancing WheelsBalancing Wheels

It is highly recommended that all four wheel and tire assemblies be balanced dynami-

cally from the bolt holes to reduce tire wear, road noise and vibration. If a static (bub-

ble) balance is used this should also be from the boltholes.

Wheels with steel rims accept conventional clip-on weights.

Aluminum rims accept clip-on weights for aluminum wheels, the use of adhesive

weights is not recommended.

All wheels are checked for LATERAL and RADIAL run out before leaving the factory to

minimize balancing problems. If difficulty in balancing is encountered, check for im-

proper installation, balancing or tire truness. A suggested remedy to some bal-

ancing problems is to deflate the tire, rotate approximately 180 degrees on the rim, re-

inflate and re-balance.

* Warning

Check the lug nut thread engagement. The engagement must be at least equal to the

diameter of the thread; less thread engagement is unsafe and can cause loss of torque.
