    Long shot, but was wondering if anyone knew what the lateral runout spec for the 21" wheels are.

    I just bought 4 wheels off ebay. 2 of the wheels have a lateral runout of about 1 mm and seem like they'd be fine. The other two have a runout of 3mm which seems way too much.

    I don't know anything specific for Tesla, but much of the data I found around the Internet suggests that for aluminum wheels, peak-to-peak radial runout should not exceed 0.010 - 0.015 inches, peak-to-peak axial runout should not exceed 0.010 - 0.015 inches, and total combined peak-to-peak runout should not exceed 0.030 inches.

    0.030 inches = 0.5 mm, so by these standards all 4 of those wheels probably should be straightened before use.

    They're going to replace all 4 wheels and personally inspect each one before boxing them up. They're also paying the shipping back. So a bit of a delay but the seller is really stepping up.
