i am about to replace the two front tires on an rv, the rv currently has tires with a F rating, do i have to use only F rated tires , or could i put on E rated tires without causing any problems?
Depending of the weight of your RV, you may have to keep the F rating. They are 14ply where the E is 10ply. Compaire weight ratings stamped in each tire. If there is much difference, stay with the F's.
