would not do it unless you could by a pair for spares. 16.5 would be pretty hard to find in the event you get a flat far from home.

 

Damn! 15s? Cars use bigger tires than that!

When i had mine with no lift, I was running 305s with no rubbing.

 

Hmmm I have 305 50R 20's on my ram.... I would think 305 would fit on the 15 as well, but i am by no means an expert, I just tell them to go wider if they can. After 3 sets of tires I am up to the 305...

 

I have a 2007 Ram 2500 HD and I tried the 35x12.5x17 (equiv 315/70/17) on mine with eagle series 197 17x9 offset rims and it was a no go!!! They would rub while turning so bad, that i would have ripped my fender off. Luckily I already had a 2.5" leveling kit. Even with the leveling kit installed I had to trim a little of the fender lining. There are pics of my truck in the "post pics of your 3rd Gen" section. Hope this helps.

They are in my album! You can see it by clicking on my name, or you can go to the last page of "post you pics of 3rd gen" section.
