Wheel Replacement
The rims installed on each product model have been
designed for stability requirements which consist of track
width, tire pressure, and load capacity. Size changes such as
rim width, center piece location, larger or smaller diameter,
etc., without written factory recommendations, may result in
an unsafe condition regarding stability.
Wheel Installation
It is extremely important to apply and maintain proper wheel
mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER
TORQUE TO PREVENT LOOSE WHEELS, BROKEN STUDS, AND POSSI-
BLE DANGEROUS SEPARATION OF WHEEL FROM THE AXLE. BE SURE
TO USE ONLY THE NUTS MATCHED TO THE CONE ANGLE OF THE
WHEEL.
Tighten the lug nuts to the proper torque to prevent wheels
from coming loose. Use a torque wrench to tighten the fas-
teners. If you do not have a torque wrench, tighten the fas-
teners with a lug wrench, then immediately have a service
garage or dealer tighten the lug nuts to the proper torque.
Over-tightening will result in breaking the studs or perma-
nently deforming the mounting stud holes in the wheels. The
proper procedure for attaching wheels is as follows:
1. Start all nuts by hand to prevent cross threading. DO
NOT use a lubricant on threads or nuts.
2. Tighten nuts in the following sequence:.
