About the 285/45R20 size
Heavy premium SUV size on 20 in wheels, so load index is as important as speed rating. Porsche N-spec and Audi RO1 versions are tuned for those cars.
The numbers mean: 285 mm section width, sidewall height 45 % of that width, and a 20-inch rim. Overall diameter works out to about 30.1 inches. Any replacement has to match all three, and the load index and speed rating on your door sticker must be met or exceeded. Our guide on reading a tire size walks through it.

- Audi Q7 (2017-2024, 20 in)

Frequently asked questions
How much do 285/45R20 tires cost?
Expect $168–$401 per tire for a budget brand, $401–$486 for a mid-range tire like the Yokohama Advan Sport V107, and $486–$552 for a premium tire like the Bridgestone Potenza. A set of four therefore starts at about $672. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 285/45R20 tires?
285/45R20 is original equipment on Audi Q7 (2017-2024, 20 in), Porsche Cayenne (2019-2024, 20 in) and Rolls-Royce Ghost (2010-2020, 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 285/45R20 tire?
For most drivers our mid-range pick, the Yokohama Advan Sport V107, 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 Bridgestone Potenza is worth the extra. On a tight budget the Atturo AZ850 is a sound choice.
Can I replace just one or two 285/45R20 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.
