The Porsche 911 Carrera S (992) is a rear-wheel drive car with 331 kW and a kerb weight of 1,515 kg. That’s 218 kW per tonne, in the sports car tier. M cars, 911s and Corvettes. Tyres are now a core part of the car's engineering.
218kW/t
Potentially P-plate restricted. Over 130 kW/t on kerb weight. Legal eligibility uses tare mass, which usually pushes the ratio higher still. Check eligibility →

Factory sizes. Wheels get changed: your tyre placard, in the driver’s door jamb, is the authority on size, load index and speed rating.
For a mild, wet climate. Cold and snowy climates are further down.
Daily driving
At 218 kW/t, your car leans hard on its tyres under power and braking. Max-performance tyres are what cars like this are engineered around.
Also consider: if you want longer life, UHP summer.
Spirited road driving
At 218 kW/t, your car leans hard on its tyres under power and braking. Max-performance tyres are what cars like this are engineered around.
Road + occasional track days
At 218 kW/t, your car leans hard on its tyres under power and braking. Max-performance tyres are what cars like this are engineered around.
Also consider: optional track set, track.
Estimates from power and weight. The tyre placard on the driver’s door jamb is the legal minimum.

Buy the marked fitment
Tyres for cars like this are often tuned with the manufacturer and carry a mark on the sidewall: N0–N2 (Porsche), MO (Mercedes), ★ (BMW), AO or RO1 (Audi), T0 (Tesla), MC (McLaren), L (Lamborghini). The marked version can differ in compound and construction; stick to it where one exists.
Rear-wheel drive
Rear traction decides how much throttle you can use, especially in the wet. Many cars at this level run wider rear tyres (a staggered set), which can't be rotated, so budget for rears roughly twice as often as fronts. Never run worn rears.
Buying only two?
Put the new pair on the rear axle, even on a front-driver. Grippy rears keep the car stable when braking or cornering in the wet; worn rears are what cause spins.
From the factory: 245/35 ZR20 95Y XL front and 305/30 ZR21 104Y XL rear (Standard 20/21-inch). Wheels get changed, so check your car's tyre placard, in the driver's door jamb, before buying.
218 kW per tonne (293 hp per tonne), from 331 kW and a 1,515 kg kerb weight. That puts it in ratio's Sports car tier.
For everyday driving, max performance summer tyres. Good options include the Bridgestone Potenza Sport, Continental SportContact 7, Michelin Pilot Sport 4S. Always match or exceed the load index and speed rating on the car's tyre placard.
Probably not. At 218 kW per tonne on kerb weight it is over the 130 kW/t limit for P1 and P2 drivers in NSW and Victoria, and for under-25 P-platers in Queensland. Legal eligibility uses tare mass, which usually pushes the ratio higher still; check your state's vehicle lookup.
Cars in the Sports car tier typically run Y-rated tyres. The legal minimum is whatever your placard, on the driver's door jamb, specifies.
