Tires
Before mounting tires onto wheels make certain that the rim size and contour is
approved for the tire as shown in the Tire and Rim Association Yearbook or the tire
manufacturers catalog. Also make sure the tire will carry the rated load. If the load is
not equal on all tires due to trailer weight distribution, use the tire rated for the heaviest
wheel position.
All tires must be matched to within
3
/4" of the same rolling circumference per the tire
manufacturers instructions. Do not use tires that fail to meet this criterion. Doing so
may result in unstable operation and significantly reduced service life.
Use tire mounting procedures as outlined by the Rubber Manufacturers Association
or the tire manufacturer.
Inflation Pressure
Correct tire inflation pressure for both the 215/75R 17.5 tires and the 255/70R 22.5
tires is 125 psi and is the most important factor in tire life. Inflation pressure should be
as recommended by the manufacturer for the load. Pressure should be checked cold
before operation. Do not bleed air from tires when they are hot. Check inflation pres-
sure weekly during use to insure the maximum tire life and tread wear. Use the tire wear
diagnostic chart to help you pinpoint the causes and solutions of tire wear problems.
NOTE: Tire wear should be checked frequently because once a wear pattern be-
comes firmly established in a tire it is difficult to stop, even if the underlying cause is
corrected.
