should the diameter of my tires( oem 400 explorer)be the same? i have the recomended pressure and the tires aren't equally 25" tall. would this cause drivetrain wear?

 

ok, on any atv tire, they usually will not be the actual hieght that is on the tire i.e.- 25 26 or 27 inches tall. So if you are running stock tires or any other tires for that matter and the diameter is what is recommended then you are ok. On my honda 300 the stockers were 23, and 24's. When I bought my vampsI bought 24 and 25's. You have to keep the stock ratio but if I had put 25's all around there might have been a possible problem, simply because on the stock bike it had a 1 inch smaller tire on the front than on the back? You got that, I know it was kind of confusing, let me know if you need anything else.
