The tire sidewalls will possibly flex enough to absorb some shock. If the overall diameter of the tires is LARGER than the original outside diameter of the F20 tires, you will be putting more strain on the drive train. If the outside diameter of the combine tires is SMALLER, the strain on the F20 parts will be lowered. There are tooooo many variables here to make blanket statements about the life expectancy of those parts! But in general..... if the rear tires are a smaller diameter, and the total weight of the tractor is close to the weight of the F20 in working condition, the drive train will take a lot of abuse as long as it stays in the lower two gears. The tires will slip (hopefully) before the parts break! Turning a shaft faster allows more hp to be transmitted with the same torque. Too much torque is what will break your parts. That doesn't mean, however, that the F20 rear end is going to last a long time if the engine is turning 8000 RPM!
