Hankook Ventus Evo 245/35 R21 Tesla Model S 20,000 miles October 11, 2025
I fitted these front tires to my Tesla Model S Performance Ludicrous in November 2024. Despite driving quietly, without excess, these tires are already worn out and this after less than 20,000 km and less than a year. They are much worse than the ones that were originally fitted, namely Michelins.
The driving feel is pleasant but without any real big change if I compare them with the previous mounts. In conclusion, I would say that the tire is expensive and not very resistant to use. Its lifespan seems quite short compared to other brands. I ordered new tires from another brand because this one does not fully fulfill its mission.

I have used for tesla s. At 6 mm level I decided to change to another tyre model as these ones seem not safe anymore

Continental ContiSportContact 5 P 245/35 R21 10,000 miles December 22, 2018
This is now the second set of these I have had. If I am lucky, I can get 10,000 miles out of them. Now going over to Falken FK510's, as they are supposed to be better all round, including £40 a tyre less. These lack grip in the dry, and the traction control light is always on limiting the power, which means my 0-60mph is slower than it could be at 3.9 seconds.
