I also have a LS, different model with 25 x 8.5 x 14 front tires. I may be replaceing mine soon. I agree that the tire circumference needs to be the same for a 4x4. It seems to me any 25 x 8.5 x 14 tire would have 25in diameter and would have the same approximate circumference. I know from stock car raceing the tires are not all exactley the same circumference, however they should be close enough. Wear on the rear tires may come into play however. I am no expert by any means. If some one else with more experiance could help out here it will be appreciated. Ahilley welcome!I’m wanting to replace my front tires on my LS mt235e ag tires 7-14 with industrial 25-8.5- 14 tires Do I have to replace the rims or will the original rims work?
