Even though it came stock with 31s
To clarify my statement of running 265/75R16's with no problem, I have 2" OME lift with them. When i got it it had stock control arms. No rubbing issue at full lock. Without the lift I would have to agree with Chris. Your loss of uptravel will make it ride poorly. Every bump will want to hit a bumpstop. Bare minimum with 32"tires would be 2" spacer pucks. And only while you are waiting to get the springs.
And that 30.6" is only when new. They will quickly become 30" or less.
That's 31.6", which is closer to 32". They'll fit with a 2" lift.
Technically they'll fit without a lift, but it will ride like shit.
