Installation Instructions

Before installing wheels:
1. Prior to mounting tires, please verify that the wheel size, number of holes, bolt circle diameter, offset, configuration of the mounting sides, and nuts are compatible with the vehicle. Then test fit the wheels to the hub to confirm clearance.
2. Observe the load rating decal on the wheel. Do not exceed the vehicle weight or tire diameter specified.
3. Check that the attachment nuts match the thread diameters and pitch on the vehicle. Also, the seats of the nuts that hold the wheels are of three types: tapered, rounded and flat. Should the shape of the nuts not match the wheel, they will not properly tighten and could come off while the vehicle is moving.
4. Always use new accessory valves. If the valves are not properly inserted in the valve holes, air leaks may occur. Also, please do not reuse valves once they have been removed.
5. After the tires are mounted, adjust the balance of all the wheels. Improper balance can cause vibration during driving. It is also advisable to have the wheels aligned.
6. Tighten nuts to the recommended torque of the vehicle manufacturer. If an impact wrench is used, first tighten to a low torque and then use a torque wrench to tighten the lug nut to the recommended torque.

Multi-Piece wheels:
1. Multi-piece wheels require extra care when mounting tires. These wheels may have a special sealant between the rims and the centers. This seal must not be touched with any tire mounting tools. If a tool contacts this area, the seal may be damaged and cause a leak.
2. When the tire valve is close to the seal, use caution in installing and removing the valve to prevent damage to the seal.
3. DO NOT TIGHTEN THE SMALL WHEEL ASSEMBLY BOLTS. They are torqued to 25 foot-pounds at the factory and should not need retightening. If any appear loose, contact ForgeLine for instructions.

After the wheels are installed on the car:
1. After the wheels have been fitted onto the vehicle, check that they do not come into contact with any part of the body or the suspension system. (When checking the front wheels, turn the steering wheel all the way left and right.)
2. Before driving, always check the air pressure in the tires. For low profile tires in particular, insufficient pressure reduces the tire’s ability to absorb impact and induces added stress on tires and wheels.
3. The lug nuts can become loose during the first 100 miles after the wheels are fitted or rotated. Use a torque wrench to make sure the nuts are at the recommended torque.

Forgeline prohibits doing modifications to the wheels. Modifications that include machining, welding or disassembling are extremely dangerous and can reduce the wheel strength or cause air leaks that can lead to broken parts or accidents. We will not acknowledge any claims concerning wheels that have been modified by the user.
