They match the tire size to the horsepower. It is pointless to have more tire then the tractor can make use of.
If you look at nearly every MFWD tractor in Europe they have wider tires than the same tractor in the US. Same with MF and CaseIH. A slightly wider tire is going hold up out the mud better than a narrow one. I realize there is a point at which you can have too much tire for a given tractor.
