If it's only a scratch, not a dent like what driving above a pothole will make,
you might be able to DIY fix it, see numerous Youtube videos,
or to get it professionally repaired, it might cost from $50 to $200 per wheel.
Note: When doing parallel parking, I added a profile where I set my side rearview mirrors
to be slented in such a way that I can see the rear wheel and the street curbside.
Also the rear view camera video shows clearly on the Tesla screen the track of the car with two white lines.
Note: Compared to other cars that I have been driving, the Tesla steering circle is much wider,
so when doing parallel parking, the car don't let you steer the car close to the side curbside.
You often need two or three manoeuvers to complete a parallel parking or a U-Turn compared to other cars.
