Omni Trail STR/AST tire care and maintenance guide

Proper inflation pressure is essential for optimum tire performance, safety, and fuel economy.  Check for proper inflation pressure at least monthly while tires are cool, as tires will warm up from use after several miles so it is best to check before driving.  Use a quality handheld accurate air pressure gauge.  It is best to occasionally have your Americus STR/AST tires inspected by a professional tire shop, as it is difficult to tell just by looking at radial tires whether they are under-inflated or over-inflated.  Furthermore, when operating a vehicle equipped with radial tires, it is difficult to notice when a tire has gone flat or nearly flat since the handling of the vehicle may not deteriorate significantly.  Remember to always maintain inflation pressure at the level recommended by the vehicle manufacturer as shown on the vehicle placard, on the vehicle certification label or in the vehicle owner’s manual. 

Evidence of air loss or repeated under-inflation always requires expert inspection to determine the source of leakage and tire removal to determine repairability.  To avoid injury, NEVER attempt to re-inflate a tire that has been in operation severely under-inflated.  Progressive air loss may result from a variety of conditions such as punctures, cuts, curbing, impacts or partial bead unsealing.  Some installation or fitment causes for air loss are (1) incomplete bead seating, (2) tearing of the tire bead caused by a machine tool due to insufficient lubrication or improper adjustment, and (3) leaking valve core or rubber valve components.  These should be corrected or replaced when problems are detected and/or whenever tires are replaced.

Under-inflation is the leading cause of tire failure and may result in severe cracking, component separation or complete loss of air.  Under-inflation reduces tire load carrying capacity, allows for excessive sidewall flexing and increases rolling resistance, resulting in potential heat build-up and mechanical damage.  Maintaining proper inflation pressure is the most important thing you can do to help promote tire safety, durability and maximize tread life.

Over-inflation will deteriorate ride quality, reduce braking ability and generate unwanted vibration.  Overinflation also increases the chances of impact damage.

Don’t overload your tires

The maximum load capacity stamped on the sidewalls of STR or AST tires. Never fit P-metric tires or LT tires on any utility trailer. STR and AST tires are specifically made to run max PSI and carry greater loads than equivalent size P-metric or LT tires.
