I am thinking of buying a set of Super Swampers radials 37-12.50-20 for my 05 Dodge Ram 1500 SLT. 4x4. 5 Lug

My question is, will they fit?? Can these fit on my truck without a lift? If not what size lift would I need for them to fit? I really like the way they look.

I'm sure the answer to this is somewhere in the forums but I have limited time and can't read through thousands of posts right now. And I don't really want to learn all about tires by doing all the research. I have to do enough reading and studding for my Job in the Military lol..

Any help would be greatly appreciated..
