Static measurements were made of the dimensions and area of the contact envelope between commercial tyres and the road surface, for a wide range of wheel-loads and inflation pressures. The contact envelope area for each tyre size is found to be very nearly constant over the manufacturer's recommended working range for the tyre. Tests on moving wheels indicate a small increase in contact area, but this factor is unlikely to be of importance in calculations of induced stresses in road pavements and bridge decks. (Author)
