Tires: Description and Operation
General Description
The factory installed tires are designed to operate satisfactorily with loads up to and including the full rated load capacity when these tires are inflated
to the recommended pressures. The following factors have an important influence on tire life:
-
Correct tire pressures
-
Correct wheel alignment
-
Proper driving techniques
-
Tire rotation
The following factors increase tire wear:
-
Heavy cornering
-
Excessively rapid acceleration
-
Heavy braking
Tread Wear Indicators Description
The original equipment tires have tread wear indicators that show when you should replace the tires.
The location of these indicators are at 72 degree intervals around the outer diameter of the tire. The indicators appear as a 6 mm (0.25 inch) wide
band when the tire tread depth becomes 1.6 mm (2/32 inch).
Metric Wheel Nuts and Bolts Description
Metric wheel/nuts and bolts are identified in the following way:
-
The wheel/nut has the word Metric stamped on the face.
-
The letter M is stamped on the end of the wheel bolt.
The thread sizes of metric wheel/nuts and the bolts are indicated by the following example: M 12 x 1.5.
-
M Metric
-
12 Diameter in millimeters
-
1.5 Millimeters gap per thread
Tire Inflation Description
This vehicle has been engineered to operate up to the stated load capacity with wheel and tire assemblies of the type, size, construction, and
configuration as originally installed. Maintenance of the tire inflation pressures is critical to the continued satisfactory performance, handling, and
operating economy of the vehicle. Operation with incorrectly or improperly inflated tires can adversely affect vehicle performance and may contribute
to the following:
-
Reduced fuel economy
-
Tire overloading
-
Shortened tire life
-
Excessive tire wear
-
Uneven tire wear
-
Vehicle handling concerns
Inspect the tire pressures when the vehicle has not been driven for at least 3 hours or not more than 1.6 km (11 mi) and when the tires are cool to the
touch.
Tire inflation pressures should be inspected monthly and before an extended trip and adjusted to meet the specifications listed for the particular
vehicle. Replace any missing or damaged tire valve stem extensions and/or caps to prevent the intrusion of water and contaminates.
One pound per square inch (psi) equals 6.9 kilopascals (kPa). The following table illustrates the conversion of kilopascals to pounds per square inch:
