Global Specialty Polymers Application Engineer | ExxonMobil
During the last 30 years, ExxonMobil Chemical has performed a series of surveys of passenger car and truck / bus radial tires to evaluate the influence of halobutyl rubber on inflation pressure loss rates (IPLR) of tires acquired globally. Previous studies have also evaluated the impact of innerliner compound formulations and liner gauge on inflation pressure loss rate as related to tire performance in various static and dynamic laboratory tests.
The purpose of this most recent body of work is to evaluate the controlled on-vehicle performance of passenger car tires as a function of inflation pressure utilizing well known industry test methods. It was then determined if connections exist between the on-vehicle test results to laboratory testing where applicable.
This presentation will demonstrate impact of inflation pressure of the tire on rolling resistance, fuel economy, treadwear, handling, and other important performance measures.
