On my L275, the front has 7.0-16 from the factory. 4ply tires is what came on it. When I replaced them I put 6ply on because of the FEL and that made an enormous difference. For me, 10 ply would be extreme over kill.The tire on the tractor now is a 7.0-16 10 ply tire. I have a front end loader on the tractor.
