This is the Michelin Pilot Sport Cup 2 in 315/30ZR21 (105Y) XL, the rear tyre size for the Porsche 911 GT3 Touring (992). It is Michelin's road and track supercar tyre, engineered to put the GT3 Touring rear-axle power down with strong dry grip while staying road usable.
The GT3 Touring blends full GT3 performance with an understated, road-focused character, and its rear tyres control traction on power. The Cup 2 uses Multi-Compound Technology 2.0 for grip and drive with everyday usability. This listing is for one single rear tyre. The GT3 Touring uses two rears (315/30ZR21) and two fronts (255/35ZR20), also available as a full set.

Yes. 315/30ZR21 is the correct rear size for the 992 Porsche 911 GT3 Touring, 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 Touring is rear-drive with a high-revving naturally aspirated engine, so the rear tyres govern traction and stability on power. The wide 315 Cup 2 gives the drive and composure that make the car satisfying, with road usability the Cup 2 R cannot match.
The Cup 2 is the more road-usable choice with a 240 treadwear rating, while the Cup 2 R is the more extreme track semi-slick. For the road-first GT3 Touring the Cup 2 rear is usually the better fit.
Front is 255/35ZR20 and rear is 315/30ZR21. This page covers the single rear tyre. For the complete car, choose the Cup 2 full set of four instead.
