Money Saving Tips on Trailer Tires

 
KNOW ... the maximum capacity and inflation pressure of the tire being used.

KNOW ... that a tire's capacity is governed by the amount of air inside. For example, an 11-22.5 load range fused as a dual has a capacity of 4760 @ 75 PSI. The carrying capacity of a tire cannot be increased above the maximum rated load by increasing its inflation pressure.

KNOW ... that if one tire in a dual set is underinflated, the other is overworked and the underinflated tire will wear irregularly. Neither tire will give satisfactory service.

KNOW ... that if both tires in a dual set are underinflated or overloaded, they will run hot because of overflexing. Excessive heat buildup is the greatest single cause of the deterioration.

HOW will knowing these facts help save money? Follow these simple rules.

• Whenever new tires are mounted, recheck inflation 24 hours after mounting because normal tire growth during this period will reduce original inflation pressure.
• Check inflation before each trip when tires are cool. Use an accurate tire gauge. (Check gauge periodically against a master gauge.)
• Inflate to the pressures required for the maximum load to be carried. (For sustained high speed driving, pressures should be increased to 10 PSI over normal recommended levels.)
• Use metal air retaining valve caps on each tire to insure air seal during operation and to keep out dirt and moisture.
• Never "bleed" tires to reduce build-up of pressure. Tire temperatures increase when the tire is in service, causing build-up in tire pressure. Build-ups of 10 to 15 PSI are normal.
• Never reduce tire pressure to obtain softer ride. This is a dangerous and costly practice as excessive tire heat may cause tire failure.
• Never install a used tube in a new tire. It will wrinkle or buckle because it has been stretched from prior use.
• Never install an undersized tube. It will reduce the air retention quality and overstress the tube splice.

• Under-Inflation causes abnormal tire deflection, which builds up excessive heat, running the risk of failure. It also causes irregular wear.
• Over-Inflation causes tires to run hard and makes them more vulnerable to impact and other road hazard damage. It also causes irregular wear.
