Bird,
My tires are currently at their furthest in position. I measure 50" to the widest point on the tire and 38" from the center cast ridge of the rubber. I have r4's. My axle has 3 more positions out on each axle but I'm pretty sure to use the last one I have to turn the hub around which would be a further inboard adjustment. Each position adds about 1" on each side making my total possible width 54" to the outermost point on the tire and 42" to the center of the tire. I suppose the difference in tires might affect the comparison though. I am assuming that I cant use the outermose setting because that would put the face of the hub beyond the end of the axle. Does anyone have any info on this??
