I know theres probably tons of threads out there on this, but im lifting my 4runner with the OME kit (BJ spacers and rear coils).

I'm pretty set on Goodyear Duratracs, thinking about going with a 33x12.5x15 tire. What offset and backspacing do I need for the best fitment? Don't want the tires sticking out that much but a bit is ok. Any help is appreciated.

 

knowing what model rig you're trying to put these on will greatly help.

in general, due to the width of a 33"x12.5" tire, you'll need wider than stock wheels per manufacturer's recommendations (so like an 8" wide vs 6") that have less back spacing so the wheel and now wider tread/sidewall bulge tire clear your a-arms - otherwise the alternative is getting a wheel diameter large enough to clear all this stuff (but that's pretty large diameter). Since the stock BS is 4.75", you need approx. 1" more room to fit a 2" wider tire - so I believe the BS you're looking for is 3.5-3.75".

I run 33x12.5 Toyo's on 15x8-3.5" BS and have around .5" clearance between sidewall lugs and my a-arms.
