Tire Replacement & Repair

Description

Tires are designed and engineered for each specific vehicle. They provide the best overall performance for normal
operation. The ride and handling characteristics match the vehicle's requirements. With proper care they will give
excellent reliability, traction, skid resistance, and tread life.
WARNING!
Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire failure.
In order to maintain the speed capability of the vehicle, replacement tires must have speed ratings equal to or
higher than those fitted to the vehicle as original equipment. If tires with lower speed ratings are fitted, the vehi-
cle's handling may be affected and the speed capability of the vehicle may be lowered to the maximum speed
capability of the replacement tires. To avoid an accident resulting in severe or fatal injury, consult the tire man-
ufacturer in regards to maximum speed ratings.

Replacement Procedure

Note the following guidelines when replacing a tire:
• It is recommended that tires equivalent to the original equipment tires be used when replacement is needed.
• Failure to use equivalent replacement tires may adversely affect the safety and handling of the vehicle.
• The use of tires smaller than the minimum tire size approved for the vehicle can result in tire overloading and
failure.
• Use tires that have the approved load rating for the vehicle and never overload them.
• Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire failure and
loss of vehicle control.
• The use of oversize tires may cause interference with vehicle components. Under extremes of suspension and
steering travel, interference with vehicle components may cause tire damage.
Perform the following when replacing a tire:
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the tire and wheel assembly.
3. Deflate the tire completely before removing the tire from the wheel.
4. Use lubrication such as a mild soap solution when dismounting or mounting tire.
5. Replace the tire with a tire approved for the vehicle.
6. Use tools free of burrs or sharp edges which could damage the tire or wheel rim.
7. Before mounting tire on wheel, make sure all rust is removed from the rim bead and repaint if necessary.
8. Balance the tire and wheel assembly.
9. Install the tire and wheel assembly and install the wheel mounting nuts.
(Tighten: Wheel mounting nuts to 110 N·m)

Repair Procedure

Note the following guidelines when performing a tire repair:
• For proper repairing, a radial tire must be removed from the wheel.
• Repairs should only be made if the defect, or puncture, is in the tread area.
• The tire should be replaced if the puncture is located in the sidewall.
