Seems Discout tire is into grinding down the rim mount flange. Where it bolts to the rotor. This is supposed to remove corrosion on rims. I told them one time in the past not to do it, but they still did.
They use a fairly course 3M Roloc disc. I think they are trying to mitigate vibration from corrosion. I feel like they are going to cause run out over time from doing this. I left a tire/steel rim for a flat repair yesterday.
Then realized I forgot to tell them not to do it, and called and told them don't bother to grind it down because the rims are only about a 1 year old, and not corroded. He assured me they would not.
Picked up the rim put in in the back of my truck, then I thought I would check if they had ground it, and found they did. I'm about ready to not buy tires anymore from them. One location the guy who worked there told me they started doing the procedure, then stopped doing it, then started again. I guess for someone that has a lot of corrosion it would probably help. But are they doing the rotor flange as well?
I just look at it as they are mindlessly doing it whether it needs it or not. The rim they did yesterday was a painted steel rim. With maybe a spec of light rust. By the time they did their grinding I had about 6 sq inches of bare metal. So I just painted the bare metal when I go home. I bought this car new Dec 2017
