If the springs are still good you can get 30's under it. My old one had tired leaves and I fit 31's with a set of AAL's but I had to clearance the inner quarter panel so they wouldn't rub when stuffed.
Well I put on 265/70r15 BFG's All Terrain. I bought them used (5,000 miles) for $250 including nissan rims. The look good but alittle stuffed. I think a 2" lift would really look good. Anybody need nissan rims?
