The rim width will be dictated by the tire section width and/or the tread width. The general rule is that the flange-to-flange width of the rim should be a minimum of three-quarters of the tire section width. The maximum flange-to-flange wheel width should be equal to the width of the tire tread. Narrow tires on wide rims tend to make the outer edges of the tire curl in toward the center. The result is less tread on the road, increased tire wear and a harsher ride. At high speeds, centrifugal action can pull the tire beads away from the bead seat on the rim.
Wide tires on narrow rims create a poor bead seal and force the tread to assume a convex shape causing abnormal tire wear, reduction of control with a somewhat smoother ride.'
