Does anyone have a preferred national tire shop that uses the latest tire changing machines and doesn't scuff/chip the rims ?
Really don't want to get my powder-coat rims messed up on the first install. Never had my stock or aftermarket rims messed up by the local shop. But don't want to take the chance. Heard some powder-coat chips off easier on tire changer versus factory painted wheels.
Powder coating if applied correctly (this also mean the prep work) is more durable than most paints.
It hard to compare factory powder coating to having it done, it all has to do with budgets. This goes for factory wheels as well. The same MAZDA wheel is manufactured in about 3 different countries. On my MAZDA 3 wheels are from Mexico and one from China all where on the car new from the dealer.
As for a company that changes tires, IMHO I would simply ask the manager or shop manager who is your best tire tech. Explain to him/her your concerns about your really nice wheels. If they even smirk let alone go into a defensive mode about how well all their people are.... IMHO PASS go to another shop.
Its not the equipment so much as it is slowing down and doing the job correctly. Also make sure they use the nylon cover for the breaker bar and use plenty of installation lube (not just water). You can and should remind them of this. If they take offence pass on them go to another shop.
I would prep the wheels in advance by removing all the wheel weights and meticulously cleaning the wheel both front and back.
I would hang out at the traditional YELLOW plastic chain at the end of the garage door that say employees only and watch the complete procedure. If you see something that you question shout out and POLITELY ask. A real professional will be happy to explain or answer your concerns and questions.
Before you load them up to take home or before they lower your vehicle down ask if you can look over the completed work. Look for any accidental damage or scratches. If they are bad or can be seen as in the front of the wheel address this now. Once you leave no one can really argue the prof where that damage happened.
You will be surprised but many shops have a person who will fit the requirements. I would also tip them like a 5 or 10 even if that shop does not allow tips to the service bay techs its the thought that counts and will be remembered next time you need your wheel done.
