I have been wondering lately if its possible to put a wider rim and tire on walkbehind. It seems if you could get a tire about twice as wide as what normally comes from the factory it would greatly reduce rutting. I don't have a big problem with this, but Ive never understood why the tires are so small in the first place. The walkers have wide low profile tires, why not have wider tires on a smaller walkbehind. Let me know if this is a dumb idea.
