Well as I put in the header my 2006 Durango SLT with the 5.7ltr Hemi came with 18" wheels and tires when I purchased it. I thought it was standard but apparently that was some kind of special order or something. I mean I like the 18" and that is not the problem. The other day I wanted to check the condition of my spare tire and when I pulled it down it was a nice brand new never used spare only it was a 17". I am not sure what the truck would run like with one 17" tire if I had a flat?? So I proceeded to look for a 18" steal rim for a spare. I can't find them not sure if they make them? So now I have to purchase a wheel aluminum like what is on the truck now so I can mount an 18" tire on it for a spare. Any one have any comments or run into the same problem??
