Abstract |
One option for reducing soil surface compaction resulting from the passage of lightly loaded vehicles is to reduce the inflation pressure of conventional tyres below the minimum currently recommended by tyre manufacturers. This paper describes an investigation of one potential problem, collapse of a tyre when subjected to large side forces, which might result from this approach. Three types were towed sideways on concrete at inflation pressures down to 0ยท4 bar (6 lb/in2) at constant radial tyre deflection while the side force generated and tyre sidewall deflection were monitored. There was no tendency for the tyres to collapse but the trailing sidewall did buckle. It may therefore be concluded that from the safety aspect that the tyre is insensitive to this type of loading. The effects of large tyre deflections on the vehicle stability as well as the effect of side forces on a rolling tyre should be investigated before any recommendation is made on the safety of using conventional tyres at pressures below the minimum currently recommended.
