I know what your all going to say...

Look that up under the FAQ's, but I couldn't find anything definitive. I want to go with either a Mickey Thompson ATZ or Toyo MT's. One guy says he's running a tire one size taller, but the he never comes out and says that is all he could fit. It mentions the stock tire size and doesn't get too far into squeezing the largest tire possible on a 3rd gen ram. I know that backspacing is a big issue with these stock 20's and I don't like the idea of running spacers even a little bit.

So, what is the biggest sized tire that you can put on the stock 20" rim with no lift? Any pics?

 

35s with a level...you can also use the search function...

 

It depends on the year. Pre 06 with torsion bars could run 35's with just a level. 06+ can run 35's with a level, but they will rub slightly at full lock and when going over speedbumps. It's kind of pointles to run a 35 if it's going to rub on small bumps and when turning. I had to add a body lift to accomodate 35's on my 07.

 

What about with no level either? Also, what is the maximum width?

 

not gonna work and it will look too crowded in the wheel wells

 

If it rubs with a level, it will definately rub without one.
