About the 305/30R20 size
The mainstream mid-engine supercar rear size. Because the C8 Corvette uses it too, availability and price are better than for most exotic sizes.
What the numbers on the sidewall mean
A 305/30R20 tire is 305 millimeters wide, its sidewall is 30 percent of that (about 3.6 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 27.2 inches. Every replacement has to match all three numbers, and the load index and speed rating on the placard inside the driver's door have to be met or exceeded.
Our guide on reading a tire size walks through the markings, and this one lists every load index and speed code.
Our three picks, side by side
One tire at each price level from what the retailer stocks in this size, with the mileage warranty and UTQG grades as published by the manufacturers and their retailers. Treadwear is the number to compare: it is a relative wear rate, so 700 should last roughly twice as long as 350 on the same car.

Winter and this size: summer tires are not winter tires
Many tires sold in this size are summer tires, and the manufacturers advise against driving them in near-freezing temperatures: the compound hardens, grip drops sharply and the tread can crack. They also carry no M+S or 3PMSF marking, so a car on summer tires fails Colorado's Passenger Vehicle Traction Law outright on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, unless it is all-wheel drive with at least 3/16 inch of tread; fines start at $130. If the car is driven year-round in a state with real winters, either run an all-season or all-weather tire in this size or keep a second set of winter tires, often on a smaller, narrower wheel that is also less expensive.
None of our picks in this size, the Nitto NT555 G2 and Nitto NT555 G2, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Frequently asked questions
How much do 305/30R20 tires cost?
Expect $149–$353 per tire for a budget brand, $353–$546 for a mid-range tire like the Nitto NT555 G2, and $546–$671 for a premium tire like the Goodyear Eagle F1 SuperCar 3R. A set of four therefore starts at about $596. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 305/30R20 tires?
305/30R20 is original equipment on Ferrari 488 GTB (2016-2019, rear), Ferrari F8 Tributo (2020-2023, rear), Lamborghini Huracan (2015-2024, rear), McLaren 720S (2018-2023, rear), Audi R8 (2017-2023, rear), Chevrolet Corvette C8 (2020-2024, rear), Chevrolet Camaro SS 1LE (2017-2024, rear), Chevrolet Camaro ZL1 (2017-2024, 20 in rear) and Porsche 911 (2017-2019, 20 in rear), among others. Always confirm with the sticker inside your driver's door, because trim levels and wheel packages can change the size.
What is the best 305/30R20 tire?
For most drivers our mid-range pick, the Nitto NT555 G2, is the sweet spot of price and tread life. If you keep the vehicle a long time or drive in heavy rain and snow, the Goodyear Eagle F1 SuperCar 3R is worth the extra. On a tight budget the Nitto NT555 G2 is a sound choice.
Can I replace just one or two 305/30R20 tires?
On a front- or rear-wheel-drive car, yes: replace in pairs on the same axle and put the newer pair on the rear. On all-wheel-drive vehicles most makers want all four replaced together, or a new tire shaved to match, because a difference in circumference strains the drivetrain.
