Nondestructive Estimation of Resistance of Tire Construction to Tread Wear

Conventionally, tires are made with cross-bias cases. In Europe, however, there is increasing interest in other constructions that enable vibration characteristics to be chosen to suit the vibration transmission characteristics of the vehicle. Since construction is an important factor in controlling tread wear, an estimate must be made when initial information about vibration is available, so that unprofitable designs will be given low priority. This paper summarizes the nondestructive techniques used in estimating tread wear resistance of various tire constructions, both in the laboratory and on the drawing board.
