Sorry Wayne, I don't know the size of the tires but your post reminded me of this Dodge 1/2 ton running around my neighborhood with what looks like 18s or even 20s, like those found on Escalades and Navigators. But the oddest part about this set up is that this 1/2 ton is a 4X4. Yes, I was speechless when I first saw it, definitely unique, but..... yah. I even saw this guy at the beach with his truck, keep in mind the tires on this truck are those low pro less aggressive tread tires. I don't know, I can't see those rims holdin up well on a truck this size, unlike Dual Designs which are designed for the load these look like they're gonna fold on the first curb climb adventure. I do like those 22 1/2 inch big rig tires I'm starting to see more and more of, I think those look cool. OK I'm done. Good luck Wayne!
