Every RG-family wheel is cast and flow-formed, not forged – ADVAN’s own English page mistranslates the RGIII. The D means deep rim. And ADVAN publishes neither a weight nor a load rating for any of them.

ADVAN Racing is a product line of The Yokohama Rubber Co., Ltd. – and the only major Japanese wheel maker that publishes its full manufacturing process. Casting at 700C, slant moulds, flow forming, T6 plus special treatment, and an 8,000-ton forging press.
