The Stovebolt Site Forums The Parking Lot Big Bolts Need help on the DESIRABLE "Widow Maker" rims!

You measure the ID of the tire or the OD of the rim which is impossible with a tire mounted. However, if they have lock rings, they are not tubeless and not the RH 5° wheels. If you look on the side of the tire, it will give you the size of the tire. It will probably be something like 7.50x20 or 8.25x20 the 20 denoting a 20".
