15" rim hole. They have rock rash...a lot, but there are no leaks and lots of tread left. There are cuts and slits but never loose any air. Great for a trail or mud rig. I drive to work on them a few times a month but I would not daily drive them. Just want to be honest. The only reason I am selling is to move up to 44s. $500 located in Bradenton FL, can meet in Plant City if needed
