What 275/45R20 tires means
The size code breaks down into exact measurements. The 275 is the section width in millimeters (about 10.83 inches across the widest part of the tire). The 45 is the aspect ratio, meaning the sidewall height is 45% of that width — here roughly 123.8 mm, or about 4.87 inches. The R means radial construction, and the 20 is the wheel diameter in inches this tire mounts on.
Add it up and the overall tire diameter is about 29.74 inches, turning roughly 678 revolutions per mile. Those numbers matter because they set your speedometer and odometer accuracy — staying close to this diameter keeps readings honest. Sidewall height affects both ride comfort and clearance, while a wider section width influences grip and how the tire fits within the wheel well.
Vehicles & uses
This is a common fitment for modern SUVs, crossovers, and performance sedans running 20-inch wheels. Sources covering this size list it across passenger SUV/crossover, highway-terrain, all-terrain, and ultra-high-performance categories — reflecting how versatile the size is. Confirm the size on your door placard or existing sidewall before ordering, since the correct fitment depends on your specific vehicle.

How to choose
Season: Summer tires maximize dry and wet grip in warm weather; all-season tires balance year-round usability; winter tires are built for snow, ice, and cold. Match the type to your climate and how you drive.
Treadwear & UTQG: The Uniform Tire Quality Grading treadwear number gives a relative sense of expected tread life — higher generally means longer wear, though a specific mileage warranty is the more concrete promise.
Load index & speed rating: The two-part code after the size (for example, 110V) states how much weight each tire can carry and its rated top speed. Choose ratings that meet or exceed what your vehicle's placard requires.
Warranty: Mileage warranties vary widely by model, so compare coverage when two tires are otherwise close on price and performance.
