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.
The numbers mean: 275 mm section width, sidewall height 45 % of that width, and a 20-inch rim. Overall diameter works out to about 29.7 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.

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, 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 Michelin Pilot Sport EV is worth the extra. On a tight budget the Kumho Ecsta PA51 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.
