    I recently purchased a new to me 1999 K2500 Suburban and the first thing I will need (want) to replace are the wheels and tires. I see that full set of 16.5 wheels/tires will be cheaper then the same sized wheels and tires in 16" What gives?

    What do I lose or gain with the 16.5 vs the 16" wheels? My truck will be used on the road 90-95% of the time. I will be stuffing 33x12.5 under it. One of the main reasons I am looking at the 16.5 is because I loved the BFG AT's on my yukon, and they are not available in 33x12.5 in the 16" size, but are available at 16.5"

    Thanks,

    The only thing you'll lose by going with 16.5" rims is a safety bead. This only comes into play if you run tire pressures under 15psi on the trail. I've heard of some guys running 10psi with 16.5's and no trouble. But much lower and you'll pop the tire off the rim. Advantages include low cost, better availability, and cheap used tires.

    You can get a 285/75/16 BFG AT that is very close to that size.
    It should be mounted on a 8inch wheel.

    I ran that size on my truck for 35k miles. You will need to adjust the torsion bars a bit.

    I had the 285's on my old Yukon. According to the BFG website if I put them on an 8" wheel they come out to be :

    LT285/75R16/D 11.3 x 32.9
    LT295/75R16/D 11.6 x 33.5
    LT315/75R16/D 12.1 x 34.7 (on an 8.5" wheel)

    Whereas the 305/70 is much closer to a 33x12.5 coming in at 33.1 x 12.2 . The problem, for me, is that the AT is not made by BFG in the 305/70. :-(

    So, I ended up getting Mickey Thompson Classic II's on the 16x8 wheel. Fantastic!! I just ran down to the used tire shop yesterday and tossed on four 'decent' GoodYear Wrangler AT/S' in 305/70. They fit really well and the whole look of the truck is changed. There is a tiny little ammount of rub on the front pasenger side, when I do a sharp left, but that is for another post. ;-)


    Thanks,
