The Porsche 911 GT3 RS uses the same tires.
As soon as the new Chevrolet Corvette Stingray C8 entered production, the conversation switched to when we may see the even more powerful Z06 version. In the C7, this model was good for 650 horsepower and 650 lb-ft of torque, so expectations are high for the new one. While not too much is known about the new Z06 yet, it could use the 5.5-liter flat-pane crank V8 from the C8.R race car.
We do have some new information gleaned from Musce Cars & Trucks about the upcoming Z06's wheel and tire size, though, an important part of the powerful 'Vette as they'll be responsible for managing all that grunt effectively. It's expected that the high-performance C8 will use 20-inch front wheels with larger 21s at the back. Optional carbon-fiber wheels should be available, too, both of which corroborates a rumor we first heard much earlier this year.
These wheels will likely be wrapped in 275/30R20 front tires with the rubber at the back measuring 345/25R21. Last year's Z06 had wheels measuring one inch less front to back, and which were 0.4 inches narrower. The report goes on to say that track-ready Michelin Pilot Sport Cup 2 R tires will be used.
These tires will be custom-made for the Z06 and feature a tread compound that benefits traction under hard acceleration and cornering. As is evident in the pictures, these tires have an especially prominent outboard shoulder and broader tread ribs. The inside shoulder has deeper notches which improve performance in the wet by quickly dispensing with water.
However, as with many types of performance rubber, these tires will do their best work in warmer, drier conditions. They sell for up to $920 each, so Z06 owners must be prepared to spend a lot on replacements. There'll be time to save though because the launch of the Z06 might be pushed as far back as early 2022, despite dealers taking early reservations for it.
The other downside of these tires is the risk of hydroplaning, especially when they wear out. But when conditions are right, the Z06 should be a beast, especially with the extra traction of the mid-engined C8. It's sure to be well worth the wait.
