Tire fitment question

[Wilhelmus Schreurs]

Mike: Here are some facts: 8.25 inch rims - 7000 lb rating 9.00 inch rims - 9000 lb rating 12R tire rating - 6780 lb rating - less for doubles 315 tire rating - 9090 lb rating - less for doubles We went from the 8.25 to 9 inch rims as well as changed to the larger 315 tire due to the allowable weight rating, all increased to the 9000 lb rating. We have not experienced any problem with the tires scrapping either aired up or down, with the exception if the front tires are not straight on the aired down position. With the weight facts listed above, why would anyone put a 315 tire on a 8.25 rim, they have done nothing to increase the weight rate value because the weakest point now is the rim at 7000 lbs Bill 1988 40WB XXV "Anniversary Special Edition" Kitimat, B.C.
