Literally just picked up my car after having the new tires installed (Michelin Pilot Sport 4 All Season F: 265/40/21 R: 295/40/21). I've only done a couple laps around my business complex so I can't report on road feel yet. I can confirm no rubbing on U-turns or turning into a steeper driveway.
Last week, I had to bring in my Tesla to the Van Nuys Service Center for an issue with my charge port. Part of the service visit included an assessment of the tires on the car. They gave me back a "3mm tread remaining" with the advisement to not replace my tires at this time. Are you f'ing kidding me? Look at the pictures I attached with the steel belt showing on the rears. Hilarious!!! Thankfully I ignored Tesla's advice and replaced the tires anyway.
As others have posted, I love the new look and feel of the car. It looks like I lowered it and the ride height is slightly higher. Both are great changes that I was going for. It's funny too because my local tire shop is owned by a friend of mine and he's located directly next door to my own business. Even when he was ordering the tires for me, he kept asking, "Are you sure they are going to fit?" I kept reassuring him that they would indeed fit as I had seen pictures of other peoples' MYP on Tesla Forums and they were fine. After he gave me the car back, he said, "This is how it should have come from the factory. These look way better than the factory size and there's plenty of clearance." I'm looking forward to some longer drives later this week and I'll report back the results. Thanks again to those of you who posted so much information and pics of the finished result.
