I have read on here about where/how/when to rotate tires, I have a different question....I just got my 2020 Model Y, from Tesla, 1 month ago. It has 42,000 miles and the tire tread depth is good and seems even. Can I assume that Tesla rotated the tires before I got it? If not, how can I tell when I should start doing the rotations? The tires appear to be pretty new but I don't know for sure. Thanks for any input.
