Really depends on who you have removing your wheels. If you are doing it yourself, you can easily manage to remove the tire without removing a ton of dip. Also, if the tech is really good, he will avoid ruining the dip. However, at the end of the day, its $5.68 to redo the wheels and touch them up.. So really, you just have to understand that every two years or year, you're gunna have to touch up the wheels when you get new tires. It takes $20 and 30 minutes of you're time.
Here are my wheels about a month ago when I got new tires. Notice, theres not really any loss of dip.. its mostly sealant grease or whatever that stuff is they use.
Here is the first time I got new tires, I went to a cheaper tire place. There weren't any high quality technicians working on my car there..
