Montering av däck

MONTERING AV DÄCK PÅ EN FYRHJULSDRIVEN TRAKTOR

The mounting of tires on a four-wheel-drive tractor must be done with great care in order to produce the best driving results and maintain the tires’ service life. Generally, the actual rolling circumference (R.C.) of a front tire should be 1 – 3 % (lug pattern max 4%) higher than the rolling circumference calculated using the gear ratio. Excessive positive lead in the front tires can cause quick wear and reduce mileage, while insufficient lead in the front tires will make the tractor more difficult to steer.

Check the Technical tire manual of the tractor in question for detailed instructions on the calculation of rolling circumferences (gear ratio). When changing the tire size or type, always check the relationship between the rolling circumferences and make sure that the combination is within the limits given by the manufacturer.

EXEMPEL PÅ BERÄKNING:

The basis for the calculation is the gear ratio between the front and rear axle, with which the rolling circumference of the required front tire can be calculated.
