    Question widest tire on a 16X7 wheel

    I have stock wheels on a 2002 Suburban, they are 16X7, what is the widest tire I can safely/properly have installed on these wheels.
    Thanks,
    Don

    285 width is about the widest I would go on stock rims. The challenge there though is that to get a decent 285 width truck tire for the 16" rims, you are probably looking at 285/75R16 for size which will also make the tires considerably taller so I would suggest making sure that you have enough clearance that the larger tires will not rub when installed. If you aren't looking to increase the height of the tire, I would stick with a 265 with. Something like 265/75R16 will not rub and is a good size. Depending on what your factory tire size is, 265/75R16 or 265/70R16 should also keep you fairly close to the original height which would keep your speedometer correct.

    If you look at the approved rim widths published by tire manufacturers (you can find tire specs at most tire manufacturers website or sites like tirerack), they want to see rim widths no less than about 65% of tire width. That makes the widest approved tires on a 7 inch wide rim about 10.5 inches, or a 265 series tire. From there, it depends on how strictly you (and/or your installer) want to be about those guidelines.

    Agreed... I've read about a lot of people with the GM 8 lug wheels (16x6.5 or 16x7) running 285 width tires, but not all technicians or companies will install them. I'm running 245 width tires on the 6" wide rims on the front of my F350 without problems, but I would suggest not going wider than a 265 on yours.

    Agreed with checking the tire manufacturers site and probably 285's.
    Now that I say that I will say that I ran 315/75/16 (Kumho Road Ventures) on my stock 16x6.5 rims for about 1.5 years until I needed new tires and bought new rims with them. That may or may not have contributed to the tires wearing out in around 24k miles. Had to play with air pressure a little bit to find the proper psi for even wear. There was obviously a bit of sidewall bulge, but didnt have any other issues.

    probably one of the best pictures to show the 315's on 6.5

    Thanks for the replies.
    Stock tires were P265/70/16
    The current tires, on it when I purchased it used, are LT265/75/16 Nitto Terra Grapplers
    I don't need tires right away, but I would like the widest look I can get without buying new rims, think I'd be alright with 275/75/16.
    I have a readylift leveling kit I am going to install this weekend, 2.5" frt / 1" rr.
