I'm looking to upgrade from the stock/OEM 18" wheel on the Advance model to a 19" or 20" wheel. I'd like to get a wheel that is similar in weight (or lighter if possible) than the OEM wheel. I've done some searching, but cannot find the weight anywhere. Has anyone that has replaced their OEM wheels weighted them and/or know what they weight? The weight of the stock wheels for the base model or the dealer upgrade diamond cut pattern wheels would be helpful as well.
