Motor vehicles for transporting heavy loads over long distances began to be designed in the 1920's. Pneumatic tyres, which by then were used on many passenger and light trucks, were recognized as the best way to cushion the load with the added benefit of low rolling resistance. As the available pneumatic tyres were limited in load capacity, the simple expedient of using two tyres on each axle end solved the problem of carrying a heavy load. Dual pneumatic tyres began to be used on heavy trucks in the early 1930's. Advances in tyre materials have greatly improved the endurance of truck tyres. It is now feasible to replace virtually any dual tyre set with a wide base single tyre having the same diameter and load capacity. Although the trucking industry in the United States has been reluctant to adopt wide single tyres, these tyres are becoming prevalent on heavy trucks in other industrialized countries, particularly in Europe. This paper reviews current knowledge of wide base tyre characteristics, in comparison with those of a conventional radial truck tyre used in dual applications. Some performance characteristics discussed are stopping distance, hydroplaning, and vertical force transmissibility. Field data on pavement deflection produced by wide base tyres, in comparison with dual tyres, are also reviewed.
