SELECTED SPARE TYRE SYSTEMS, REQUIREMENTS AND PERFORMANCE
The spare tyre and wheel unit is the only spare part supplied with modern vehicles. Because of the weight and dimensional problems connected with the storage of the standard spare tyre, wheel and tyre engineers are working with the vehicle industry to develop special spare tyre systems. These systems are designed to satisfy the requirements of the vehicle users and manufacturers. The main requirements are identified and quantified. Two systems have been developed: the "tempa spare" and the "special spare". The tempa spare is a tyre/wheel unit with considerably reduced dimensions compared to the standard tyre it replaces, and it is designed to operate at a higher inflation pressure. The wheel for the "tempa spare" is generally larger in diameter, narrower in width and has more "in set" than the standard wheel used on the vehicle to obtain optimum performance. The "special spare" tyre has basically the same dimensions as the standard tyres on the vehicle but is considerably lighter. It is designed to operate at inflation pressures similar to those used for the standard tyre, and it fits the standard wheel. The test results presented show that both the selected spare tyre systems meet the established requirements. A review of existing governmental regulations is presented as a guide for prospective users. For the covering abstract of the conference see TRIS 392374. (TRRL)
