Q: What is the Curb Guard ring on the Road Warrior wheel?

It is a replaceable outer ring that takes the hit when you scrape a curb. Scuff it, and you swap just the ring to restore the look, rather than refinishing or replacing the whole wheel, and you never have to break down the tire to do it. The narrower 8.5-inch width helps too: it lets the OEM tire bulge slightly past the rim, forming a pillow of sidewall that shields the wheel lip. Curb rash stops being an expensive problem.
