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.
The numbers mean: 275 mm section width, sidewall height 45 % of that width, and a 21-inch rim. Overall diameter works out to about 30.7 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.

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) and Chevrolet Blazer EV (2024, RS 21 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 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.
