i have a 06 dodge 2500 and im doing the 2inch leveling kit. what is the biggest tire i can fit without having to lift it any higher??? if anyone knows the specs (width/size) please tell me. i needs tires real bad.. well only the back ones..lol.

 

35x12.50x17 will fit great with a 2inch leveling kit. I am running them on stock suspension but am soon upgrading to lorenze's kit. I think ptgarica is running 35x13 on an aftermarket rim with close to the same backspacing.

 

I'm running 315/70 BFGs without a leveling kit and only get a slight rub on the control arms at full lock

 

You can stuff these 37"s in w/o a lift, but my aftermarket alloys have a bit more than the factory backspacing.

 

some people ahve a bit of rubbing with 315/70/17s on their and some dont. I dont

 

I think it depends on their wheels' backspacing.

 

these are 35x12.50's and i have no rubbing at all

 

You have to remember that the stock wheel is 8". For most tire manufacturers, they will only recommend up to a 285 or 295 tire for a 8" wheel. If you want to put on 35 or 37, the tire manufacturers will recommend that safe minimum diamter to be at least 9". Since you are putting a wider tire on a smaller wheel, the sidewalls will be pulled in causing your tires to bulge. The middle of your tires will then wear faster than the edges of your tire. To get the tire to run flat, you have to run rediculously low amounts of air (20-25psi).

If you want to safe in the safe recommended ranges for your stock wheel, look for a 285 or 295. I had the BFG 315/70/17s and they DO rub at full wheel lock, and they DO not wear evenly.
