Man, am I disappointed that I spent $2K on the induction wheel option. What moron engineer designed a costly wheel in which the rim itself protrudes out further than the tire? All you have to do is touch the curb lightly while rolling and the finish is wasted. Even though I'm generally pretty careful, sometimes it just happens. The aluminum alloy used is so soft that it gets shredded so easily. I've been smoothing the lumps out with a sanding block and then using a paint pen to make it black again. Works fairly well to the casual observer. Until you touch the curb again. Terribly disappointed with such a poor design from this otherwise outstanding company.
