I have a 2002 Durango and I need to find a set of tires for it. What is the biggest tire I can put on there with the stock ride height without any rubbing.

I searched but I only found a sticky about Ram tire sizes.

 

Well if you have 15" rims you can use 31x10.5x15 tires with no trouble.
You can use 32x11.5x15 but you need to crank the front torsion bars and put in some helper springs out back.
These will rub in the front at full lock.

I'm not sure what size to use right offhand if you have the 16" rims.
I'm betting that someone will show up mighty quick and let you know.

You can also do a search because I'm pretty sure someone had asked a similar question just a week or two back.

 

31 inches is the maximum diameter that you can fit, i believe that is 265/70/16 or 31x10.5xZ (where z is your rim size, 15 or 16 inches)

 

I have 16s.

 

265/70/r16. There you go bud. I have a set on mine, and they fill out well.
