About the 275/45R20 size
Model X rear and German SUV 20 in size, V/W/Y with 110 XL load. Model X owners should buy acoustic-foam tires; the fronts are 255/45R20.
What the numbers on the sidewall mean
A 275/45R20 tire is 275 millimeters wide, its sidewall is 45 percent of that (about 4.9 inches tall), and it mounts on a 20-inch wheel. That works out to an overall diameter of roughly 29.7 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 110V on the Lexani LX-Thirty and Hankook iON evo AS SUV (2,337 lb per tire, rated to 149 mph) and 110H on the Continental 4x4 Contact (2,337 lb per tire, rated to 130 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.

The same tires in neighboring sizes
The Hankook iON evo AS SUV, our mid-range pick here at $386.99, is also stocked in 285/45R21 ($472.99), 265/35R22 ($425.99), 255/40R20 ($413.99) and 255/35R21 ($253.99).

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.

Winter on an EV in this size
Electric vehicles are heavy for their size and deliver full torque instantly, which is exactly what loosens a tire on snow. Most EVs in this size are all-wheel drive and pass 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, on the vehicle alone, as long as the tires have at least 3/16 inch of tread; a rear-wheel-drive version needs tires marked M+S, 3PMSF or rated all-weather by the manufacturer. Fines start at $130. Whatever you fit, keep the load index at or above the door placard, since EV tires are usually XL rated for the battery weight, and expect any winter or all-weather tire to cost some range through higher rolling resistance.

Frequently asked questions
How much do 275/45R20 tires cost?
Expect $115–$175 per tire for a budget brand, $175–$317 for a mid-range tire like the Hankook iON evo AS SUV, and $317–$444 for a premium tire like the Continental 4x4 Contact. A set of four therefore starts at about $460. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 275/45R20 tires?
275/45R20 is original equipment on Tesla Model X (2016-2024, 20 in rear), Porsche Cayenne (2011-2018, 20 in) and BMW X5 (2019-2024, 20 in front), 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 275/45R20 tire?
For most drivers our mid-range pick, the Hankook iON evo AS SUV, 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 Continental 4x4 Contact is worth the extra. On a tight budget the Lexani LX-Thirty is a sound choice.
Can I replace just one or two 275/45R20 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.
