CAUTION: Before installing wheels. remove any build up of corrosion
on the wheel mounting surface and brake drum or disc mounting surface
by scraping and wire brushing. Installing wheels without good
metal·to-metal contact at the mounting surfaces can cause the wheel
nuts to loosen, which can later allow a wheel to come off while the
vehicle is moving, possibly causing loss of control.
Dual Tire O peration
The outer tire of a pair on dual wheel installations generally wears
faster than the inner tire. If this occurs, reverse position of the tires
to equalize wear and achieve optimum tire life.
In addition, when trucks are driven continuously on high crown roads,
an increase in air pressure of from 5 psi (35 kPa) to
in the outside tire of each dual produces maximum tire life. Be sure
not to exceed the inflation pressure limits shown in the Tire & Wheel
Load and Inflation Charts.
Alignment And Balance
Proper front-end alignment improves tire tread mileage. Your vehicle's
front-end suspension parts sh,ould be inspected often and aligned when
needed. (See the Maintenance Schedule Folder for more information).
Ball joints have built-in wear indicators and some movement in the
joints is normal. Improper alignment will not cause the vehicle to
vibrate. However, improper toe alignment will cause the front tires to
roll at an angle which will result in faster tire wear. Incorrect caster
or camber alignment will cause your front tires to wear unevenly and
can cause the vehicle to "pull" to the left or right.
Proper tire balancing provides the best riding comfort and helps to
reduce tire tread wear. Out of balance tires can cause annoying vehicle
vibration and uneven tire wear such as cupping and flat spots.
Traction
decrease in driving, cornering, and braking traction occurs when
A
water, snow, ice, gravel, or other material is on the road surface.
Driving practices and vehicle speed should be adjusted to the road
conditions.
When driving on wet or slushy roads, it is possible for a wedge of water
to build up between the tire and road surface. This is known as
hydroplaning and may cause partial or complete loss of traction,
vehicle control, and stopping ability. To reduce the chance of traction
loss, follow these tips:
Slow down during rainstorms or when roads are slushy.
1.
Slow down if road has standing water or puddles.
2.
Replace· tires when tread wear indicators are showing.
3 .
Keep tires properly inflated.
4.
If your vehicle has TPC radial tires (see "Tire Replacement" in this
section) your tires are designed to provide better snow traction than
bias or bias belted tires without snow treads. However, if you equip
your vehicle with snow tires, use snow tires of the same size, \oad range,
