Experimental Studies of the Size Contact Area of a Summer Tire as a Function of Pressure and the Load

Abstract

Vehicles in depending on the segment and destination vary in size, type and power drive unit. These factors directly affect the total weight of the car and thus the type and size of tires. The choice of tire size depends on the power generated by the drive unit, which through the interaction of tire-pavement is to be transferred to the surface. The parameters affecting the field of contact with the ground is the value of the tire pressure and load on each wheel unit. Depending on the size of the rim, tire size and the number of people transported and / or goods manufacturer gives the recommended pressures for front and rear axle of the car. The effect of changes in pressure and load on the size of the surface area of contact selected summer tires with the road.
