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 recommen-
dations, 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 POSSIBLE 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 fasteners. If you do
not have a torque wrench, tighten the fasteners 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 permanently 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.
