That's an excellent point. I rotate when I swap Winter vs Summer and I clean the inside of the wheels when I do.
Takes me longer than 20 minutes though when I do
I also carefully mark all the wheels and I know how I rotated them and how I like to rotate them.
Since I'm swapping wheels I don't need to load them into the car either (which is more work than swapping them !!)
It's Win Win Win doing it yourself.
P.S. When I was kid I had a 69 Dodge Charger that I rebuilt. I spent every spare moment for a couple years working on it and every penny I made as well. That education of how things work and go together was priceless. Learn your CAR !!! Yes, your hands might get dirty.
