Winrun R330 265/35 R21 Tesla Model S 1,200 miles May 11, 2025
Had to buy these in a pinch for the rear of my car. Absolutely horrendous steering feel and handling. Super unpredictable and felt awful at higher speeds. It wandered all over the road. Comfort was average and can't comment on life span as these stayed on the car just long enough for me to drive home. Replaced with Michelin PS4S and the difference is astronomically high. Would look at other options.

Hankook iON Evo AS 265/35 R21 Tesla Plaid 1,000 miles October 2, 2024
Original Michelin Pilot sport 4S was worn to 1.6mm after 18000 km. ABS activates in curves, which is annoying as it results in uneven wear on inside rim of the tire. Hankook ion seems not have the same problem, after testing at 300 kmh on German Autobahn, and also slow driving at curvy roads seems like no ABS issues so far. They're also far less noisy than Michelin, and hopefully wears out less quickly.

This Tesla ABS issue seems to be with all tires used, Pirelli, Michelin and Hankook S1 evo 3. But ion is good so far...

Where this data comes from

Owner ratings are submitted through the review form on this site, naming the tyre, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tyre tests indexed by size, and label values from the EU EPREL database.

About the TR Score

The Tyre Reviews Score rates each tyre out of 10 using independent test results and the full body of owner reviews, so you can check a car-specific ranking against the wider evidence.

Who does the testing

Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
