Before mounting tires onto the 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.
N.B.-:-T
HE CAPACITY RATING MOLDED INTO THE SIDEWALL OF THE TIRE IS NOT ALWAYS THE
PROPER
RATING FOR THE TIRE IF USED IN A TRAILER APPLICATION.
Use the following guidelines :
• LT and ST tires. Use the capacity rating molded into the tire.
Use tire mounting procedures as outlined by the Rubber Manufacturer's Association or the tire
manufacturers.
Tire inflation pressure 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 pressure weekly
during use to insure the maximum tire life and tread wear. The following tire wear diagnostic
chart will help you pinpoint the causes and solutions of tire wear problems.
Component Standard wheel
Tire size ST 215/75 D 17.5 in
Typ e Pneumatic
Size 406,4 mm (16 in)
Tor qu e
34 Nm (25 ft lbs) - Initial torquing
136 Nm (100 ft lbs) - Intermediate torquing
406 Nm (300 ft lbs) - Final torquing
The tire and rim are bonded together, both must be replaced if either is damaged.
Tire wear should be checked frequently because once a wear pattern becomes firmly established in a tire
it is difficult to stop, even if the underlying cause is corrected.
