    My buddy has a 99' Tacoma with 3" Bilstein coil overs, 1" BL, and All Pro UCA's. He is stepping up to KM2's in size 35x12.5x17s. He is going to do a 17x9 Pro Comp Steel Wheel. I was trying to help him decide if he should go with a 4.5" or 3.5" backspace. He wants the tires to stick out past the fenders some. What size backspace should he run?

    He has already been running 315 all terrains and they rub minimally right now, but he is going to tub his wheel wells if necessary.

    3.5" is definitely the better choice of the two.


    4.5" is the stock backspacing for 1st gens.

    yeah, I think the 3.5 is going to be the best. I've got 4" BS now with 35's (but with a 3" BL :() and I rub the frame rail when turned hard. Thats my main clearance issue. The truck came this way though, so until I can afford new wheels, i'm stuck with it.

    Probably. But a least it won't rub the UCA's like the 4.5's would.

    Bt you have a 6" lift and a 2nd gen. So your wheels stick out almost 2" more than stock. His will only stick out 1 more inch than stock.
    You also have a second gen. See above.

    I think you are going blind, because I said that nofords had a six inch lift, and that you had a second gen. Check again please.

    Completely different backspacing requirements for 1st vs. 2nd gens.
