Hi, my CPO 90D had new tires (OEM Goodyear Eagle T1) put on the rear before I purchased it in 2020. Nearly 2 years and 14k mi later, the front tires were wearing very badly and getting thin, so I had them replaced with same tire as the rear, hoping to get some decent miles out of the set with timely rotations. I asked the tire installer to assess the rears and consider rotating them to the front and putting the new tires on the rear. He advised that the rears were showing some uneven wear on the insides, but you "should have your best tires on the front" so he left the rears in place and just installed the new tires on the 2 front wheels. He advised getting the alignment checked to cure the inner wear on the rears.
I had the alignment checked yesterday. The alignment shop said that these vehicles do not have a camber adjustment in the rear, so the inner wear is not fixable. They also generally said that Teslas have the most extreme camber and toe parameters of any vehicle, which they believed was a performance thing. They said the parameters are way outside ones from BMW, Mercedes, Audi etc. I figured the weight of the car was a factor too. They aligned the car within the tolerances, but erring on the side of tire longevity after we discussed the parameters.
The car drives night-and-day better now with the new tires on the front and the alignment-- I'm very happy. However, I'm concerned about the excess wear on the rear inside and the fact it can't be fixed via alignment. I'm thinking it would be a good idea to actually rotate the tires to maximize longevity in the set despite the tire guy's recommendation-- what do you think? Also-- is any of this that either shop said blowing smoke up my butt or are they right on? Thanks!
