Tire analysis method and system for determining characteristic parameters of an agricultural tractor

A tire analysis method for determining characteristic parameters of an agricultural tractor provided with two front wheels supporting two front tires and with two rear wheels supporting two rear tires, the method comprising:

• mounting a first rotation sensor on a first wheel, wherein the first rotation sensor is configured to measure a number of revolutions made by the first wheel and is separate and independent from the agricultural tractor;
• mounting a second rotation sensor on a second wheel, wherein the second rotation sensor is configured to measure a number of revolutions made by the second wheel and is separate and independent from the agricultural tractor;
• while driving the agricultural tractor along a straight path, measuring the total number of revolutions made by the first wheel and by the second wheel under actual operating conditions of the agricultural tractor;
• measuring, via a distance sensor, a distance traveled by the agricultural tractor while driving along the straight path, wherein the distance sensor comprises a receiver which is attached to a body of the agricultural tractor and a beacon placed in a fixed position on the ground nearby a travelling path of the agricultural tractor;
• dismounting the first and second rotation sensors from the respective wheels after the agricultural tractor has been driven along the straight path;
• determining at least one actual characteristic parameter for verifying tire setup for operation of the agricultural tractor, using the total number of revolutions made by the first wheel and by the second wheel while driving the agricultural tractor along the straight path, wherein at least a first characteristic parameter accounts for variations in actual operating conditions including at least one of:
• tire pressure, tire wear, and load per axle, and wherein at least a second characteristic parameter accounts for at least the measured distance traveled.
