I had 33x12.5x20 Toyo Open Country M/T on my 2006 Quadcab. I still have the stock suspension. I did use 1/4 inch spacers because of the width. They are an awesome tire. However, i'm dont run them in the summer. I took them off yesterday with only 1200 miles on them. Thinking about selling them, i'll prolly post them "for sale" later tonite.

 

stock dodge 17" rims are 8" wide and you can run a 12.5 in tire on them, I had 295/70/17 on my stock rims, but 33 x 12.5 would have fit the rim
