ETRTO (European Tyre & Rim Technical Organisation) is working within the UNECE GRBP framework on a tyre abrasion rate method for regulatory purposes. The feasibility study identified a vehicle test on public roads as a suitable method for passenger car tyres. Validation tests were done on 11 different tyre specifications, tested 4 times each with this method, to estimate test dispersion due to influencing parameters. Test conditions are defined in terms of ambient temperatures, driving style, vehicle settings, reference tyre and measuring intervals. The reported Tyre Abrasion Rate is a relative value versus a fixed reference tyre in tyre weight loss per kilometer driven per carried ton [mg/km/ton].

摘要

ETRTO (European Tyre & Rim Technical Organisation) is working within the UNECE GRBP framework on a tyre abrasion rate method for regulatory purposes. The feasibility study identified a vehicle test on public roads as a suitable method for passenger car tyres. Validation tests were done on 11 different tyre specifications, tested 4 times each with this method, to estimate test dispersion due to influencing parameters. Test conditions are defined in terms of ambient temperatures, driving style, vehicle settings, reference tyre and measuring intervals. The reported Tyre Abrasion Rate is a relative value versus a fixed reference tyre in tyre weight loss per kilometer driven per carried ton [mg/km/ton].
