Hey yall! I am getting ready to install a tuff country 6in lift on my 03 Ram 2500. The recommended tire size is 37 x 12.5. My question is 1. Can I go bigger without any adverse affects? 2. Can I use the stock 17in wheels or will I have to get new wheels? I appreciate the help!

 

It's all in the backspacing, widthand offset of the wheels. You want to get as close to 6" backspacing and +offset as possible w/ aftermarket wheel. Anything less you may run into rubbing the back wheel well/fender. Especially any articulationoffroading.

As for the stock wheels. I'v seen some w/ 37" on stock wheels. You can do it. Just rotate them often and use good psi inflation. You will be more prone to cupping of the tire becuase of the size of the stock wheel width (8.0"). You may want to run a wider wheel (8.5"-9").

Anything bigger than 37" I don't think it will fit w/o major rubbing.

 

Thanks for the info. I will stay with the recommendations and get some MT wheels. I will post pics when the work is done.

 

I already rub a little with my 37's and my wheels have about a 1" offset. Id stick with 37's IMO. Good luck. Any particular reason your going with the Tuff Country?

 

6-inch lift with 37s on a Dodge is the best combination in my opinion. Chevy's look best with 6-inch and 35's, and Ford's look best with...well....who cares! I think bigger than 37s are overkill.
