I have a 2004 1500 Crew Cab long bed that came stock with P245/70R17 's on it and I would like to goto a 33inch tire. I dont really know the conversion for that. Can anyone help me with the numbers so I can order my tires.

Nice choice in truck, love the long bed. This site will help you out. I think you will want 285/70R17.

 

Thanks for the help guys, after I get the tires next week I will post pics.

 

theirs a few companys that make 33x1250/17 tires that will fit on stock rims,thats what i have check out my gallery to see if you like how they look

 

the 285/70/17 and 33x12.5x17 are going to be almost exact in size.

 

I had 33x12.5x17 Mickey Thompson MTX's before I lifted and went to 35's. Very good tire, tread lasts forever. Perfect tire for a daily driver with occasional off road use. Also rated as one of the best AT tires for use in snow (if they got that stuff where you are). Had a lot of friends when I lived up north had them on their 2wd trucks and got through the heaviest snow with no problem. I had mine on for 29,000 miles and sold them for about half what I paid for them new as they had virtually ALL the original tread. Also fills the tire well up very nicely on a stock height RAM 1500.

 

I found these and it is a good deal cause the tires are brand new but I dont think they will fit w/o rubbing what do you guys think.... http://dayton.craigslist.org/pts/414921374.html

 

2 problems - you can't use a 15" wheel, your brake calipers are too big, 17" is minimum size. And their is a problem with that add. I just double checked MT website and the MTX maximum size is 33" (which is perfect for you anyway.
And you cannot clear 35's without a lift, 33" is your max.

 

i think you can fit 35's with a leveling kit though on a 1500 right?
