THE ROAD GRIP OF COMMERCIAL VEHICLE TYRES
Tests were carried out on a range of cross ply and radial ply commercial vehicle tyres. Peak and locked wheel braking force coefficients on dry and wet surfaces were measured for speeds up to 95 km/h and maximum sideways force coefficient was measured at 30 km/h on two wet surfaces. All the tyres tested gave much the same coefficients on any one surface. The values of locked wheel braking force coefficients for the dry surfaces were lower than expected and varied with verticle wheel load.
