i'm in need of new rubber and don't want to buy factory size rubber and then want to move to something bigger half a year from now. can i fit 35s on a 15" rims with 3.75" BS with somewhat OKAY performance on the pavement with factory setup until i can afford a decent lift upgrade?

 

With flat flares and some trimming. Or with lots of rubbing...

 

I'd chop your fenders and get the teraflex leveling kit. Without he leveling kit, it's still possible but my prepared to hack and bend pinch seams. IMO the leveling kit is the easiest solution and it's only like 125.

 

Not on 15s but here is a writeup I did when I was running stock wheels with 35s and no lift. I cant imagine it would be any different with the right 15s and proper backspacing.
