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 necessarily increase vehicle GVW ratings. It is recommended that tire chain clearance guideline,
J683, from the Society of Automotive Engineers be adhered to in designing rear wheelhouse clearance.
Check tires and inflate to recommended tire pressure according to the tire pressure information provided in Owner’s Manual and tire inflation
label provided with vehicle.
Any substitution of tires may affect Speedometer/Odometer
accuracy.
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
frame rail, a cable of similar gauge 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:

If the battery is remotely mounted (other than in the engine compartment) the ‘sense’ circuit in the generator regulator shall be used. The
sense circuit consists of a 7.76 OHM 1/4 watt resistor connected in series between the ‘S’ terminal of the generator and the B+ terminal of
the battery.
