The shop I got on for this is a small shop and the guy that does MC tires is the co-owner. If he messes it up, he buys a new rim. And they let you watch the whole evolution. I’ve had 6 tires done there and not a scratch or issue. All they do is tires, so no sales clerk taking my rim and tire to the back and trying to do it.Based on my knowledge of "tire shops" there are none I know I would trust to mount a motorcycle tire. I'm happy to hear though that you have one that did not cause issues, it's rare. I've seen these guys ruin auto wheels, atv, motorcycle and even farm wheels with regularity. The guy busting the tires is usually the lowest paid and least educated. That has not changed in decades.
