TIRES
Air pressure
Maintaining the correct tire pressure is important to the safe operation of the vehicle as well as
ensuring long tread life.
Under inflated tires result in:
• Excessive tire side wall flexing that can result in sudden tire failure.
•
Excessive tread wear resulting in shortened tire life.
Over inflated tires result in:
•
Tire explosion due to excessive pressure.
•
Reduced road surface traction.
•
Increased vibration from the road surface.
•
Premature tread wear.
Unequal tire inflation may result in:
•
Uneven braking and loss of control of the vehicle.
•
Steering pulling to the left or right.
Only check the tire pressure when the tire is cold. When checking tire pressure, you must check
all tires including your spare tire.
The correct tire size and pressure can be found in the specifications list in the manual. The tire
pressure shall only be adjusted when cold (i.e., “cold” is defined as the tires’ internal temperature
matches the ambient temperature before the vehicle has been driven). Note: The front and rear
tires may have a different tire pressure specification.
Note: The front and rear tires may have a different tire pressure specification.
Tire Tread Wear
It is important to periodically inspect the tread on each tire for wear. Driving
with inadequate tread increases the risk of losing control of the vehicle due to hydroplaning on a
wet road surface. It also increases the risk of a flat tire due to road
debris. Extreme tire wear can result in sudden tire failure and loss of
control of the vehicle.
Refer to the maintenance schedule in this manual for the recommended
tire inspection interval.
Minimum recommended tread depth is 1/16 inch (1.5 mm). There are
a series of tread depth wear indicators around the circumference of
the tire. They will appear as 1/2 inch (13 mm) bands across the tread as the tire approaches its
wear limit (see illustration). The tire should be replaced if any tread depth indicator can be seen or
any part of the tread depth is 1/16 inch or less.
Incorrect tire inflation can result in sudden failure of the tire and/or braking / steering
problems leading to loss of control of the vehicle.
Never exceed the maximum pressure as indicated on the side wall of the tire. Exceeding the
maximum pressure may cause explosive failure of the tire resulting in severe bodily injury.
WARNING
DO NOT operate a vehicle if the cord is visible on any tire (see
illustration). A tire in this condition may suddenly fail at any
time resulting in loss of control of the vehicle.
