Equivalent Passenger Unit Ratios (EPUs) Tables
An equivalent passenger unit (EPU) is a standard passenger car tyre. The weight of an EPU for a new passenger car tyre is standardised as 9.5kg; and the weight of an EPU for a used passenger car tyre is standardised as 8 kg.
The following EPU ratios reflect the potential recoverable resources from the various types of tyres.
