I've used the WinRun R330 tyres on both S85D and X90D. They are great. One of the few tyres with US DOT UTQG ratings on the sidewall. Treadwear 420. Last set I put on went over 60,000Km before down to 2.2mm tread.
They are one quarter of the price of Michelins and last about 1.8 times longer. Tread depth new is 7mm. Current pricing in Sydney for 245/45R19 102W (i.e. Model S) is $101 fitted & balanced.
I am *NOT* talking about driving like an idiot. I am talking about driving to the law, and using extra prudence in the wet. The WinRun tyres totally eclipse the 'name' brands like Pirelli, Michelin, Bridgestone, etc. I have noted the limo companies using Teslas fit WinRun.
A friend with a Model S got crap mileage & performance from Goodyear Eagles. I tried Kumho once and they were total rubbish. Got less than 30,000Km from them. I have had quite reasonable runs with Falken, but the WinRun is better value.
There is a Youtube video where a Model X owner (Norway I think) compares the WinRun tyres to Michelin. He makes the same conclusion namely that the WinRun are heaps better than Michelin. I think URL is:-
I would exhort Tesla owners to *refuse* to buy any tyres which do not have warranted UTQG ratings on the sidewall. It is the law in the USA. A total lack of similar law in Australia means we get shafted by the tyre manufacturers. And remember the 'brand' means essentially nothing these days. The country-of-origin is quite variable. Many brand names made in Thailand or Malaysia.
