They are 17", tires are 35/12.5/17 I think. We took it up to the mountains last week for its first towing trip, its officially broke in! He is having a ball with it, got his brake control on it and hooked onto his 30' bumper pull camper the other day and says it runs right up to 80 with ease. Still rides like a 92 dodge one ton...
This is the kind of stuff he likes to do when we go to the mountains. I used to but at 64 I more enjoy putting around on the trails and enjoying the scenery anymore.
