This is the Pirelli P Zero Trofeo RS in 315/30ZR21 (105Y) XL, the rear tyre size for the Porsche 911 GT3 (992). It is a road-homologated, track-focused semi-slick that puts the GT3's high-revving power down with strong traction and stability.
It is built for 911 GT3 owners who want rear-axle grip and drive on track while keeping the car road usable. This listing is for one single rear tyre. The GT3 uses two rears (315/30ZR21) with two fronts (255/35ZR20), also available as a full set.

Yes. 315/30ZR21 is the correct rear size for the 992 Porsche 911 GT3, and this is the rear tyre for that fitment. The front axle uses 255/35ZR20. You need two of this rear tyre for the car.
The GT3 is rear-drive with a high-revving naturally aspirated engine, so the rear tyres control traction and stability on power. The wide 315 section and motorsport compound give the drive and composure that turn corner exits into lap time.
It is track focused and road homologated. It maximises dry grip with a semi-slick shoulder for a wide contact patch, while staying road legal. It is not intended for wet or cold conditions.
Front is 255/35ZR20 and rear is 315/30ZR21. This page covers the single rear tyre. For the complete car, choose the Trofeo RS full set of four instead.
