Just letting people know to always check the inside of your rims whenever you have a tire change where there's a mount/dismount from the rim. Also if you didn't pull the wheels off the car like I do, you should inspect the inside of the rim to ensure its not damaged. I had my 2 front tires changed out, picked up tires at the TireRack and removed the wheels myself (rears are in process of changing). I instructed the tireshop, Firestone in Santa Cruz (who did a good job for the rears last time without issue) to line up the tire yellow marks with the valves and to not lay the rim on its face. They acted like, yes we know. Well I get my rims back, cleaned up the inside of the rim before placing them back on the Roadster and found multiple gouges where the tire mounting system bit into the rim. There are over 16 deep gouges in each rim! I called them and let them know how my rims were now damaged and that they're professionals who are to not have the rims damaged at all with a tire change. The manager said they put plastic on the inside of the rim as well as a rag. I indicated that there's definitely an issue with the process or the machine and to contact the machine manufacturer for that something is wrong if their process for mounting / dismounting was properly followed. The end result was that the manager said they'll pay to have both rims repaired and to have an estimate done that they can have. What would need to happen is a dismount of the rim, sanding and filling in the damaged area, and repainting the entire rim. I may just take the money and later have them fixed since I don't want to deal with the hassle right now. Will post pics when I get a moment. So make sure to inspect your wheels when you get them back. This also happened on my Jeep rim at another tireshop, Wheel Works in Santa Cruz! In no way should your rims be scratched, nicked, or gouged after a tire change.
