using these tyres on other models

To use 107mm diameter tires on the rear axle of your vehicle and 100mm diameter tires on the front axle you must change the ratio of the gearboxes to account for the different rollout values. To do this use GP5 gears in the front gearbox and GP6 gears in the rear gearbox:

FRONT:

ARA311016 - MAIN INPUT GEAR 15T GP5

ARA311017 - MAIN DIFF GEAR 42T GP5

REAR:

ARA311018 - MAIN INPUT GEAR 14T GP6

ARA311019 - MAIN DIFF GEAR 45T GP6
