Nice tires - how do the ride & handling compare to the 22" pirellis ?
1. They feel weird at first (grippy/sticky) on the steering wheel, but you get used to that quickly.
2. PS4S's don't ride like true 22's but more like 20" wheel (just my opionion). Somewhat soft particularly if you have the comfort setting
3. The acceleration feels much more aggressive than Pirelli's. The Pirelli's felt heavy and somewhat laggy/not as responsive, almost like a shoe thats too big or just doesn't fit right.
4. The ride is a lot smoother and quieter, can barely hear the tire noise.
5. Small downfall: You need to allow sometime for the PS4S to warm up in colder temps like in the low 40's/high 30's.
6. And yes the efficiency is noticeable. Which for me was the main reason I dumped the Pirellis. So it's been well worth it.
Lastly I have no idea why Tesla uses the Pirelli as it's OEM tire. I see NO value in it what so ever. It sucks in snow, efficiency is bad and not really performance tire by any meaningful metric. I hate to sound like a broken record; But again I don't see the purpose of the OEM Pirelli's.
