My wife has a 2019 M3 SR with the standard 18" wheels. Zero problems with this car except 1.) I don't get to drive it enough and 2.) I have to fill the wiper fluid every 9 or 10 months, dammit.
So I forgot about rotating the tires for, um about 2 years now, and didn't realize how quickly she's been racking up the miles. And then this week we got a warning that the tread depth on the rear tires is low. I had no idea there could be a sensor for that. (Does it compare rotation of axle to distance traveled? Impressive.)
The tires still look fine and run smooth, and the alignment is still perfect. Rear tread depth is 4/32nds, front tread depth is 6/32nds. I *have* been careful about keeping the tire pressure correct. Any reason I couldn't have my mechanic neighbor do the job? I haven't read anything about any sensors needing to be reset or recalibrated at the dealer or anything like that. It sounds like rotating diagonally for asymmetric tires is the thing to do. Thanks! And go ahead and roast me on lazy maintenance, I deserve it, but I got spoiled by how needy this car isn't.
