Wheels and Tires
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 60 degree
intervals around the outer diameter of the tire. The
indicators appear as a 6 mm (0.25 in) wide band when
the tire tread depth becomes 1.6 mm (2/32 in).
General Description
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: M12 x 1.5.
• M = Metric
• 12 = Diameter in millimeters
• 1.5 = Millimeters gap per thread
Tire Inflation Description
When you inflate the tires to the recommended inflation
pressures, the factory-installed wheels and tires are
designed in order to handle loads to the tire's rated load
capacity. Incorrect tire pressures, or under-inflated tires,
can cause the following conditions:
• Vehicle handling concerns
• Poor fuel economy
• Shortened tire life
• Tire overloading
Inspect the tire pressure when the following conditions
apply:
• The vehicle has been sitting at least 3 hours.
• The vehicle has not been driven for more than 1.6 km
(1 mi).
• The tires are cool.
Inspect the tires monthly or before any extended trip.
Adjust the tire pressure to the specifications on the tire
label. Install the valve caps or the extensions on the
valves. The caps or the extensions keep out dust and
water.
The kilopascal (kPa) is the metric term for pressure. The
tire pressure may be printed in both kilopascal (kPa) and
psi. One psi equals 6.9 kPa.
