I'm experiencing unusually rapid wear on the front tires of my MFWD tractor. What might be causing it? The problem could be the result of "lead/lag," a condition found on MFWD tractors that can shorten the life of the front tires and cause wear and tear on the tractor's transfer case. Lead/lag refers to the relationship between the speed of the front wheels and the speed of the rear wheels. If the front tires' speed is faster than the rear tires' speed, the tractor has a lead condition. If the front tires' speed is slower than the rear tires' speed, the tractor has a lag condition. The desired amount of lead 2 percent, which means the front wheels turn 2 percent faster than the rear wheels. The Firestone Farm Tire Data Book contains information about how to accurately measure and correct lead/lag on your tractor. << Back to Questions & Answers Can’t find the answer you want?
