With my DJ Kit at +3, I was 48 inches wide. I dropped it down to +2 and put on the raptor 660 shocks and I sit right around 46. Trust me at 48" it'll handle awesome. I'm thinking you might have some aftermarket rims then with a different offset. Measure them up tomorrow if you have time.
OK I will. I'm not sure what kind if rims. They are aftermarket ...maybe ITP? Not sure -came with when purchased
