As a former discount tire employee (days of 5 were hired and only 3 could keep their job, today auditions are gone), started back in the firestone/ford recall days, and later becoming a MB Master tech, dealerships have the worst tire and rotation on the planet period. They use impacts on wheel locks... they don't torque locks either.
At my dealership it was so bad, I was made the 1 and only wheel and tire guy, 1 guy to do them all, even SLR wheels. Our president would have his family vehicles delivered to me from his other dealerships, that how bad dealership techs are at tires, few and I mean few should ever be allowed to touch a wheel and tire, let alone do flat repairs. none of them could calibrate the balancer install low pros without ripping them, I worked on hundreds of celebrities cars, loads of local sports stars from the cowboys, mavs, stars, FC club, musicians, actors, porn starts, local news reporters, and the ridiculously rich where I was paid to go to their house to remove them bring them back install and drive back out there to re install the assy... etc....
Another example my mom took her esky to caddie dealership, for the typical chrome peeling causing a slow leak, yeah the tech took a grinder to the wheel where the tire bead seals it only made it worse.
Working at discount tire was 10x harder than being a MB tech. Dealership techs... LOL and I was one, it was bonkers to watch them F up wheels & tires everyday.
I wont let any of my GM dealers touch my wheels and tires, I bought a coats tire machine and hunter tire balancer to do it myself, saving up for an alignment rack next, bet you wish I was your neighbor.
