Stonecrushers are available in 17x8, 17x10, 3.625" and 4.625" backspacings, for the 8x6.5 pattern. Without removing the tire, I have no idea how to measure..
Ken, the tires rub at the back of the tire wells. These actually do not touch the sway bars.
I'm bringing it to a truck tire alignement place tomorrow and see if they can fix it.
