Presentation

Innovative rapid dynamic abrasion test method for tire tread compounds

Predicting tire wear performance on the road within a laboratory environment is paramount in developing tread compounds, as wear testing is one of the most unsustainable, expensive and time-consuming processes in the tire industry. The well-established Grosch abrasion test on the LAT100 was designed to estimate mathematically common daily driving scenarios based on speed and energy dissipation, in accordance with the ISO 23233 standard. This presentation introduces a novel dynamic abrasion test that significantly reduces test time (by at least 12 times) while demonstrating excellent agreement with the Grosch test matrix without requiring intra- and extrapolation mathematical models.
