How Often Should I Rotate My Tires?

[Friedrich201]

I’ve got a 21 Porsche Taycan Turbo and I’m wondering how often I should be rotating the tires. I wanna make sure I’m not wearing them down unevenly; but also don’t want to overdo it.
Anyone here know the sweet spot for rotations?

The car’s rocking different-sized tires on the front and back, which complicates the process of rotating them.

Oh, I didn’t even think about the different tire sizes! So does that mean I can’t rotate them at all, or is there a specific way to do it?
