Tire Pressure Systems

According to Goodyear, under inflation is the #1 cause of tire failure. If the pressure in your duals is not the same, the diameter of the tires will differ. Since duals are bolted together, the smaller tire will be dragged. With just a 5% difference in PSI, the smaller tire will be dragged 13 feet every mile. That reduces MPG and increases the risk of a blowout. Tire Pressure Systems help drivers see low pressure before failure occurs.
