The BMW M3 Competition (G80) is a rear-wheel drive car with 375 kW and a kerb weight of 1,730 kg. That’s 217 kW per tonne, in the sports car tier. M cars, 911s and Corvettes. Tyres are now a core part of the car's engineering.
217kW/t
Over the P-plate limit. Above 130 kW/t, so P1 and P2 drivers in NSW and Victoria, and under-25 P-platers in Queensland, can't drive it without an exemption. P-plate rules
For a mild, wet climate. Cold and snowy climates are further down.
Daily driving
At 217 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 217 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 217 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.
217 kW per tonne (291 hp per tonne), from 375 kW and a 1,730 kg kerb weight. That puts it in ratio's Sports car tier.
For everyday driving, max performance summer tyres. Good options include the Michelin Pilot Sport 4S, Continental SportContact 7, Bridgestone Potenza Sport. Always match or exceed the load index and speed rating on the car's tyre placard.
No, not without an exemption. At 217 kW per tonne 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.
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.
