Abstract
Durability and end of life considerations of products are important, especially regarding microplastic pollution . Tyres significantly contribute to this problem, with nearly 30% of the microplastics originat ing from tyre wear. Therefore predicting tyre wear and improving abrasion resistance of tyres are essential to decrease the microplastics.
Tyre wear is a complicated phenomenon, dependent on multiple factors , and predicting it for truck tyres remains a challenge. This work presents research on rubber abrasion, to understand factors influencing truck tyre abrasion and current laboratory measurement methods. Multiple factors were investigated and correlations between results from LAT100 analysis and material characteristics were evaluated. Results show linear abrasion dependence on the load and a positive correlation between shear strength and a brasion.
The abrasion was tested using both the DIN abrader and LAT100, with the latter
showing better correlation between lab and road data. However, current LAT100
protocols for car tyres are suboptimal for truck tyres. It requires further improvements like increasing the energy dissipation , reduced speed, increased load and disc sharpness.
Future work will optimise the LAT100 protocol for testing truck tyre compounds
and additional compounds will be developed to better understand wear behaviour and material properties.
