"70R" should be a designation on the tire, not the rim

It would indicate a radial tire in which the height of the theoretical oval shape of the tire's inside wall is 70% of its width -- in other words, reinterpreting this very carelessly, a 70 series tire of 205mm width will have the belts roughly 145 mm above the bead seats, if it's installed on the rim size for which it was designed.
