I need to put new tires on my 21" wheels for the summer. I have 19" wheels w winter tires but ended the season last year with 21" Michelins that only lasted about 7000 miles. Has anyone found 21" tires that last a bit longer and are somewhat quiet? And can you recommend tire centers near DTC with Tesla experience? A few places I spoke with want to jack up my P85 with 4 jacks and I am a bit wary of that. Any info is greatly appreciated!
