Low tire pressure is unsafe and costly

Air loss impacts vehicle handling, braking, safety, and fuel economy. The key is to maintain the air inside the tire while "in-use" for optimum performance.

The Inflation Pressure Loss Rate (IPLR) test is a standard method to determine the rate of which the tire will lose pressure. Low IPLR means good air retention, which can minimize the "in-use" rolling resistance, improving an EV's driving range, and increasing an ICE's fuel economy.

Innerliners made with Exxpro™ 3563 elastomer have excellent air retention and can generate additional potential savings.
