    Default 285/75/16 tires on stock 6.5" rim

    i have a 2004 2500HD Silverado with the stock 6.5" rim. On all the tire websites I have looked at they say that a 285/75/16 tire should go on at least a 7" rim. Is this stretching the tire too much? I've heard a few people have ran this setup but will it hurt the tire in the long run? i want a 33" tire but don't want to be left hanging with a blown set of tires. Any advice is surely appreciated.

    The "old school rule" used to be the wheel should be around 2" narrower than the tire tread width. This allowed the tires sidewall to flex properly. I still try to follow this within reason, but people have put all different width tires on all different width rims soooo....
    I would follow the tire manufacturers recommendation for what wheel width to mount your tires on

    how is the tread wearing? I had 80 lbs in all four of mine size 265/75/16 and they are wearing pretty badly in the center so i aired down to 55 lbs, but the damage has already been done i will need new tires before it gets too snowy. How are 285s in the snow?

    You are out of the tire manufacturers parameters/specs. That is not a good idea. You don't want to be going down the road and have a front wheel blow out. I changed tires and wheels and ran into similar issues trying to find everything that fit together correctly.
