The single most important factor in tire performance and longevity is
proper inflation.
Fifty percent of all road calls are in response to failed tires--83% of
all tire failures are due to improper inflation. Under inflated tires flex more, producing more heat and increased resistance. Tests at Goodyear show that 15% underinflation results in a 2.5% drop in miles per gallon! That same 15% under inflation will shorten tread life,  cause irregular tread wear and reduce casing life. High heat build up from underinflation ultimately causes increases in separation and circumferential breaks.
This is especially critical for the inside tire.
Changes in temperature also affect pressure.
For every 10 degrees decrease in temperature there is a 2psi drop in your tire's air pressure. Tires also lose an average of 2psi per week just in normal operation.
For optimum performance, tire longevity and top fuel efficiency we recommend that you check pressure and maintain proper inflation on your tractor and trailer once a week.
This should be done out of direct sunlight and at least three hours after parking your vehicle to allow the tires to cool. A typical long haul trucker can save 100 gallons of fuel per year not to mention tire replacement and repair costs!
All of our ValvePal products are designed to help you simplify, minimize the time and maximize the results of your routine tire maintenance.
