When I bought my KRX I bought a spare wheel but without a tire. I wasn't going to buy 31 inch tires from the dealer when I could get 32's or 33's for the same price or cheaper somewhere else. Since I have a bare rim I thought I would measure the offset. The rim is 8 incheswide. The offset is 6 3/8's x 1and5/8's. The bolts that hold the beadlock ring on thread into metal inserts in the rim instead of the aluminum rim.
