Abstract—Tires are important parts of every vehicle including tractors and other off-road vehicles. Thus, structural and operational characteristics determination of the tires is too important. Tire deflection and tire contact area are functions of tractive performance. In this study an electronic system was designed in order to determine deflection of the tire. Deflection and contact area experiments were conducted by means of single wheel tester. As a result; the effects on deflection of dynamic axle load and inflation pressure were found significant (P<0.01) by utilizing variance analysis. There was a linear relationship between deflection and contact area of tire. The deflection of the tire increased with dynamic axle load for all inflation pressures tested. The deflection decreased with increasing inflation pressure. Additionally, increase in the tire load and decrease in the tire inflation pressure lead to bigger the tire contact area.
Index Terms—Contact area, deflection, dynamic load, inflation pressure, tire.
