About the 275/45R21 size
Explorer ST and Grand Cherokee Summit size, V/W with 110 XL load. Grand-touring SUV all-seasons; premium-priced.
What the numbers on the sidewall mean
A 275/45R21 tire is 275 millimeters wide, its sidewall is 45 percent of that (about 4.9 inches tall), and it mounts on a 21-inch wheel. That works out to an overall diameter of roughly 30.7 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 110Y on the Atturo AZ810 and Yokohama Advan Sport V107 (2,337 lb per tire, rated to 186 mph) and 110H on the Goodyear Eagle F1 Asymmetric 5 ROF (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 Atturo AZ810, our budget pick here at $171.08, is also stocked in 255/50R19 ($131.96), 245/35R21 ($137.96), 265/35R22 ($140.96) and 305/40R20 ($164.96). The Yokohama Advan Sport V107, our mid-range pick here at $339.96, is also stocked in 285/40R22 ($519.20), 325/35R22 ($605), 265/35R21 ($327.99) and 285/45R20 ($1,655.96). 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.

Frequently asked questions
How much do 275/45R21 tires cost?
Expect $142–$322 per tire for a budget brand, $322–$408 for a mid-range tire like the Yokohama Advan Sport V107, and $408–$560 for a premium tire like the Goodyear Eagle F1 Asymmetric 5 ROF. A set of four therefore starts at about $568. Add roughly $15 to $45 per tire for mounting and balancing.
What vehicles use 275/45R21 tires?
275/45R21 is original equipment on Ford Explorer ST (2020-2024), Jeep Grand Cherokee (2022-2024, Summit Reserve 21 in), Lincoln Aviator (2020-2024, Black Label 21 in), Jeep Grand Cherokee L (2021-2024, Summit 21 in), Chevrolet Blazer EV (2024, RS 21 in) and Mercedes-Benz GLE (2020-2024, 21 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 275/45R21 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 Goodyear Eagle F1 Asymmetric 5 ROF is worth the extra. On a tight budget the Atturo AZ810 is a sound choice.
Can I replace just one or two 275/45R21 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.
