Abstract : A frictional work of each tyre has been calculated by means of rigorous mathematical analysis and practical approximate method at cornering site. To estimate a wear life of each tyre, a relation between amount of wear and frictional work has been investigated for some period, and then another relation between residual depth of tread and operation time has been measured in-situ for several tyres of a capacity 45 tons heavy dump truck.
