An improved device was used for measuring contacts area and pressure under different load from 400 to 1100 kg (3.924 to 10.79 kN) with inflation pressure ranged from 40 to 240 kPa. The device consists of two frames. The main frame is supported on the soil and the second is used to test the tested wheel by measuring the load applied on the wheel. The tested wheel is loaded using a hydraulic piston. A full Wheatstone bridge of strain gage was mounted on the second frame to measure the load applied to the wheel. Pressure transducer was placed under the tested tire to measure ground pressure caused by the loaded tire. The AMGEPRO soft ware was used to determine tire contact area. Five models describing tire contact area were tested and compared with measured contact area to determine the closest model of experimental data. The statistical analysis shows that there was no significant difference between model-1, model-2, model-3, and measured data on the other hand there were a significant difference between model-4, model-5 and data recorded. Three models were tested to determine tire contact pressure, the statistical analysis shows there was significant difference among the models studies and data obtained. Two models are derived to describe tire both contact area and contact ressure.
