Section 10 — Tires
Check wheel lug nuts for proper torque; specifications are provided in the Owner’s Manual.
Substitution of tires of greater capacity than those offered as original equipment by vehicle manufacturer is not approved for use on original
equipment wheels. Any usage of higher capacity tires must be accompanied by higher capacity wheels. However, the wheel offset and
distance from centerline of rim to wheel mounting face must be the same as the replaced original equipment wheel to ensure proper wheel
bearing loading and clearance of tires to body and chassis components.
Increasing tire and wheel capacity does not increase vehicle GVW ratings.
It is recommended that tire chain clearance guideline from the Society of Automotive Engineers, J683, be adhered to in designing rear
wheelhouse clearance.
Check tires and inflate to recommended tire pressure according to the tire pressure information provided in the Owner’s Manual and tire
inflation label provided with the vehicle.
Any substitution of tires may affect Speedometer/Odometer accuracy, tire wear, fuel economy, ride and handling and stopping distances.
Section 12 — Electrical Battery and Battery Cables
The vehicle battery should be located and positioned to make use of the existing battery cables. If the battery requires relocation and longer
cables are required, a proportionately larger gauge wire must be used. If, in relocating the battery, the negative ground cable is attached to
the frame rail, a cable of similar gauge must be provided between the frame rail and the engine. This is required due to the heavy electrical
loads imposed by the starting circuit. To ensure proper operation of the battery cables the following chart on length, gauge and materials
must be strictly adhered to.
