Air retention matters!
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.
