Ok, well the obvious answer is that everyone should be rotating tires according to the tire manufacturers recommendation in order to not void the tire's treadwear warranty. This is usually every 7500 miles. Michielin - Tires should be rotated every six months or 6,000 to 8,000 miles. http://www.michelinman.com/tires-101/tire-care/tire-maintenance/tire-rotation.page Goodyear - 3,000 mi-6,000 mi (that SUUUCKS and only another reason I hate Goodyear!) http://www.goodyear.com/en-US/services/tire-rotation Continental - rotate your tires every 6,000 to 8,000 miles http://www.continentaltire.ca/www/tires_ca_en/themes/contiacademy/tire_service_maintenance/rotation_en.html Obviously, (assuming you drive about 25000 miles/yr) if you wait until your 12,500 mile inspection, this is going to void the tire's manufacturer treadwear warranty. Plus, it will just wear out your tires much faster anyway. Not recommended.... So then .... what are all of you doing? Are you doing it every 6000-7500? Are you having this done by Tesla (does it cost anything?) Can you use their ranger service for this free of charge? (assuming you don't have 5th tire and they pick up and drop off), or are you bringing it to their service center? Do they charge for this? Or are you just using a home (nearby) auto place? (they guy that you used to go to before you had the tesla?). Clearly, since you didn't buy the tires there...it's not free. (my place has always been "if you buy the tires here, rotation is always free"). Just wondering what everyone else's plan here is.
