    I have a 90 suburban 1/2 ton 4x4.
    I'm putting a BDS kit, 2.5 front springs and a 4" block in the rear to bring it up to level or a bit higher in the rear.
    I wanted 15x10 wheels and 33/12.50 BFGs but was told they wouldn't fit but that using 15/8 wheels would. However, I was told that by using 15/8 wheels it would cause faster wear on the tires and cause drivability issues.
    Any thoughts on this ?

    My blazer has about a 3" lift front and rear. I have 15x10 Mickey Thompsons with 33" BFGs. it rubs with tight turns, other wise ok. I haven't really done radical off-road, so can't speak to rubbing with full suspension compression

    So should I go with 32" tires to be safe ?

    That shop be smoking da crack....................Sort of.

    With that tire and wheel combo, it will force the tire to crown somewhat in the middle, so if you're running respectable road air pressures, the middle of the tire will wear faster than the rest of the tire. The only "drivability" issue this will cause is that since the tire will not have a contact patch across the width of the tire, it will be a little more susceptible to leaning than having the tire on a 10" wheel. As long as you are a decent driver and can realize and understand the changes stuff like this causes, these issues the shop has brought up will be very minor in the scheme of things.

    That's all from personal experience. I wouldn't worry too much about wear either since the BFG tires wear like iron. :D

    33x10.5R15's fit most rigs wth stock wheels, no lift, and no rubbing.

    So it sounds like this guy was FOS.
    So you're saying that with the lift described above I should have no problem using 15x10 wheels and 33 12/50 15s ??

    I prefer the 10" rims. you most likely wont have probs but every truck sits different

    If you do have a problem clearing those tires, just trim your fenders a bit... there is a guy with 2.5 lift springs on here that runs 37's..... :bow:

    So if I understand correctly, with the lift I outlined in my post above, I should be able to run 33x12.50s BFGs on a 15x10" wheel with no issues ??
    Or am I reading this wrong ?

    What I'm saying and reading is that it will prob. be fine but no guarentee cause every rig's a little different. Go for it.
