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.
What the numbers on the sidewall mean
A 285/45R20 tire is 285 millimeters wide, its sidewall is 45 percent of that (about 5.0 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 30.1 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.
In this size our picks are marked 112Y on the Yokohama Advan Sport V107 and Bridgestone Potenza Sport A/S (2,469 lb per tire, rated to 186 mph). The first number is the load index, the letter the speed rating; a tire with equal or higher values than your placard is fine, a lower one is not.
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.

The same tires in neighboring sizes
The Yokohama Advan Sport V107, our mid-range pick here at $1,655.96, is also stocked in 265/35R21 ($327.99), 275/45R21 ($339.96), 255/40R18 ($215.07) and 285/40R22 ($519.20). Useful if your vehicle came with a different wheel package, or if you are comparing an upsize: the same tire usually costs more per inch of wheel, not per inch of rubber. Prices per tire, from the retailer's feed Nov 13, 2026.
Winter on an SUV in this size
Most SUVs in this size are all-wheel drive or four-wheel drive, which is enough to satisfy Colorado's Passenger Vehicle Traction Law on the 126 miles of I-70 between Dotsero and Morrison, in force from September 1 to May 31, as long as the tires have at least 3/16 inch of tread. A two-wheel-drive version must instead be on tires marked M+S, 3PMSF or rated all-weather by the manufacturer. Fines start at $130. Four driven wheels help you pull away, not stop: a heavy SUV on worn all-seasons needs much more road to brake on snow than the same vehicle on a tire with the 3PMSF symbol, so in the snow belt choose the tire, not just the drivetrain.
None of our picks in this size, the Atturo AZ850, carries the 3PMSF symbol; for that, look at the all-weather and winter tires.

Other years and wheel packages of the same models came on 255/55R18, 285/45R21 or 255/50R19 instead, so read the placard inside the driver's door before you order.

Frequently asked questions
How much do 285/45R20 tires cost?
Expect $138–$400 per tire for a budget brand, $400–$486 for a mid-range tire like the Yokohama Advan Sport V107, and $486–$564 for a premium tire like the Bridgestone Potenza Sport A/S. A set of four therefore starts at about $552. 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) and Porsche Cayenne (2019-2024, 20 in), 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 Sport A/S 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.
