tire clearance
 

I've recently got a 97 longbed 12v and it looks like it's got 2" spring blocks at the front and 4" blocks out back. It's got 05' rims with 285/70/17 do any of you guys know if I'll have clearance issues with 305 or 315 70's?

I think those are about 33s and 35s right? is it 2wd or 4wd. for a 4wd i heard of people being able to fit 35s with alot of rubbing the 305s are what are reccomended for that kind of lift. And its 2" on the front and 4" on the back, not the other way around? your ass prolly sits kinda high. Ussualy front gets more inches on it. on a 4.5 lift they reccomend it can clear 35s but ive seen 37 on them.

You'll fit 305s fine. You'll most likely rub with the 315s but a leveling kit will fix that.

As long as you arent planning any heavy duty offroading - youll have lots of room for 305's or 315's.

The rear is the stock lift blocks, for 4wd. The front is a leveling spacer, possibly homemade.
