    I've got 285's on my CCSB D/A on stock aluminum wheels with no rubbing. I had them on aftermarket aluminum wheels but when I hit a bump in hard corners they rubbed so I switched back to the factory wheels. I have no lift, no timbrens, and no torsion bar adjustments made.

    You will rub with 285/75R16 on a stock suspension at with properly sized wheels. The biggest tire you should put on a 6.5" wide rim (factory) is a 245/75. You'll need a 7.5" wide rim to use 285's, making them stick out further at the sides, requiring trimming of the bumper and wheel liner, and torsion bar adjustments.

    I went from 265's to 285's and I am wishing I just stuck with 265's.

    I forgot that little detail, i trimmed a little bit off the front of my plastic inner fender wells while I had the wider wheels on it, so that could be why mine do not rub and q101's do. either that or he's drivin a girly truck :)

    I have 265s with no rubbing, I guess that's what I'll stay with then.

    what wheels are proper and what should or shouldnt work is a matter of opinion. what DOES work is a matter of fact. and 285's on factory gmc aluminum wheels work nicely. they look right, handle well, and have no problems holding a load. tread wear is even, and I like the looks of the factory stuff. so from a factual perspective, I say you should go 285's :):drinkup:

    I have an 06 2500HD with 245's on it now, looks like it will take a 285 but I really don't want to take the chance of any rubbing.So I will probably be looking for 265's.

    another benefit of 265s is a much larger selection of 10 ply ratings in a wide variety of brands.

    Another advantage is 265 cost a lot less than 285.

    I run 285's with no rubbing, front bumper is trimmed. I have also cranked the front and added Timberins.

    I hadnt noticed much difference in price at all. usually no more than $40 a set difference.
