As temperatures increase, tire failures increase. Heat is one of the big factors in tire failure, the biggest cause of heat on a tire is underinflation. A recent ATA Technology and Maintenance Council study found that only 44% of tires were within +/- 5 PSI of target pressure. A further study found that nearly 60% of drivers did not know the proper inflation pressure for the trucks they were driving. Add the weight of our freight with low tire pressures and we have a recipe for disaster. Thumping tires is no longer the accepted means for checking a tire. Tire pressure should be assured through the use of a good tire pressure gauge, and should be a part of every pre-trip inspection. Don’t get left on the side of the road in July, check your tire pressures and assure they are ready for what lies ahead.
Answer: No, the only way to make sure tires are properly inflated is to use a gauge.
