Description
Michelin Pilot Sport Cup 2 R Rear Tyre for Porsche 911 S/T (335/30ZR21)
This is the Michelin Pilot Sport Cup 2 R in 335/30ZR21 (109Y) XL, the rear tyre size for the Porsche 911 S/T (992). It is Michelin's ultimate street-legal semi-slick track tyre, engineered to put the S/T rear-axle power down with extreme dry grip.
The 911 S/T is a lightweight, rear-drive, driver-focused 911, and its rear tyres control traction on power. The Cup 2 R is optimised for roughly 90 percent track and 10 percent road use. This listing is for one single rear tyre. The S/T uses two rears (335/30ZR21) and two fronts (275/35ZR20), also available as a full set.

Does the Michelin Cup 2 R fit the Porsche 911 S/T rear axle?
Yes. 335/30ZR21 is the correct rear size for the 992 Porsche 911 S/T, and this is the rear tyre for that fitment. The front axle uses 275/35ZR20. You need two of this rear tyre for the car.
Why does the rear tyre matter on the 911 S/T?
The S/T is rear-drive with a high-revving naturally aspirated engine, so the rear tyres govern traction and stability on power. The wide 335 Cup 2 R gives the extreme grip and drive that make the most of the car on track.
Cup 2 R or Cup 2 for the S/T?
The Cup 2 R is the more track-focused semi-slick optimised for around 90 percent track use, while the standard Cup 2 is more road usable and easier to live with day to day. Pick the Cup 2 R rear for maximum track grip.
What is the full front and rear setup for the 911 S/T?
Front is 275/35ZR20 and rear is 335/30ZR21. This page covers the single rear tyre. For the complete car, choose the Cup 2 R full set of four instead.
