What size Tires?

[TexasDieselBoy]

OK, this may have been answered before but I will ask it again. I just bought a 2005 3500 4x4 SRW LWB 325/610 48Re. I was wondering what is the biggest tire I can fit on the truck. I am willing to put a leveling kit on possibly Daystar or Tuff Country (any recommendations on those?). I have heard I can run 315's on it but I am not 100% sure. Any pros and cons ya'll have run into would be great advice.

i've got 315's under mine, and no rubbing issues. on stock wheels and stock suspension... some say they get a little rubbing, but the leveling kit fixes that...



buy tires first, then leveling kit if needed

When did they come out with that engine??? Your TQ numbers seem a bit low for that HP :-laf



You should be able to fit 315's on there. I have them on mine with a level kit.

I believe that 35X12. 50's is the biggest tire that will fit stock suspension. Mine are actually a little bigger than the 315 BFG's that a guy at work has on his dodge. I got my 35's while still riding stock height, only rubbing was very slight on the lower control arms at full lock steering. Have since put a leveling kit on, looks way better, and just barely rubs at full right turn now. Mileage went down about 1. 5 mpg is the only down side, but the upsides make it WELL worth it to me.
