TMC 2002 Tire Pressure Study

2. TMC 2002 Tire Pressure Study Over 35,000 tires checked: 90% of tire failures examined – root cause was under inflation Only 43.6% of tires were within +/- 5 psi of target air pressures 21.7% of all dual sets had pressure mismatch greater than 5 psi 21.6% of vehicles with one tire under inflated by 20 psi or more Surveys conducted in 1995 & 1998 found that 90% of tire failures examined were caused by under inflation – 1995 and 1998 surveys of tire road debris revealed that 90% of these failures were caused by under inflation. These findings led to the 2002 Tire Study. A total of 35, 128 tires were included in database - 4786 trucks and tractors; 1301 trailers; 1500 motor coaches – operated in 174 fleets.

3. TMC Recommended Practice 235 20 minutes per 18-wheel end vehicle to check, adjust & record inflation pressures 5% psi inflation mismatch on duals causes smaller tire to “drag” Constant 20% under inflation decreases tire life by 30% Tire pressure variation impacts fuel economy (.5% to 3%) TMC suggests it takes about 20 minutes per 18-wheeled combination vehicle to check, adjust & record inflation pressures using traditional means. Inflation mismatch on a dual set of as low as 5 psi and the resulting difference in tire diameter causes the smaller tire to be “dragged” approx. 246 miles over it’s 100,000 mi. life. A constant 20% under inflation decreases tire life by 30%. Studies have shown tire pressures 20 psi below to 20 psi above target results in fuel economy variation of approx. 2% per 18-wheeled combination vehicle.
