What 285/45R20 tires means
The 285/45R20 code describes the exact dimensions of the tire. The 285 is the section width in millimeters (about 11.22 inches). The 45 is the aspect ratio, meaning the sidewall height is 45% of that width, which works out to roughly 128.2 mm (5.05 inches) tall. The R confirms radial construction, and the 20 is the wheel diameter in inches this tire is built to mount on.
Doing the math, the overall tire diameter comes to about 30.1 inches, and the tire turns roughly 670 revolutions per mile. Those figures matter because diameter and revolutions per mile drive your speedometer and odometer accuracy, the sidewall height affects ride comfort and how the tire absorbs bumps, and the width influences clearance inside the wheel well and against suspension components. Matching your factory size keeps all of these in spec.
Vehicles & uses
A 285/45R20 is a wide, relatively low-profile tire on a large 20-inch wheel, a combination commonly found on performance SUVs, crossovers, and larger sport-oriented vehicles that pair a big footprint with a shorter sidewall. The size class balances a planted, confident contact patch with the styling of a tall wheel. Because vehicle setups vary, always confirm the size against the placard on your driver's door jamb or your owner's manual before ordering.

How to choose
Season
Summer tires deliver the sharpest dry and wet grip in warm weather but are not made for cold or snow. All-season tires trade some peak grip for year-round versatility. Winter tires are the right call if you regularly face freezing temperatures and snow.
Treadwear & UTQG
The UTQG rating printed on a tire covers treadwear, traction, and temperature. A higher treadwear number generally suggests a longer-lasting compound, while performance-focused tires often trade treadwear for grip. Compare these ratings across the models you are considering.
Load index & speed rating
Always meet or exceed the load index and speed rating your vehicle requires. Many 285/45R20 options carry an XL (extra load) designation, which indicates a reinforced structure for higher load capacity. Confirm the service description matches your placard.
Warranty
Mileage and workmanship warranties vary by brand and model, so review the coverage on the product page before you buy.
