The 275/55R20 stands as one of the most popular tire sizes for modern trucks and SUVs. This size delivers an excellent balance between performance and appearance that makes it a top choice for vehicle manufacturers. 275/55R20 tires measure 31.9 inches (810 mm) in diameter with a width of 10.8 inches (275 mm). These proportions create a tire that excels on paved roads while providing solid capability for light off-road adventures.
The 275/55R20 features a sidewall height of 5.95 inches (151 mm) and circumference of 100.25 inches (2546.26 mm). The shorter sidewall compared to the 275/60R20 makes it ideal for city driving and highway performance. Each tire completes approximately 632 revolutions per mile (393 per kilometer), directly impacting your speedometer accuracy and fuel consumption. Drivers focused on fuel economy will find the 275/55R20 offers better gas mileage than larger tire alternatives.
This guide covers everything you need to know about the 275/55R20 tire size. We'll examine which vehicles use these tires, their performance characteristics, and how they compare to alternatives like 275/60R20 and 285/55R20. Understanding these dimensions and applications will help you determine if 275/55R20 tires are the right fit for your vehicle's needs.
Reading tire dimensions correctly helps you make informed decisions about fitment and performance. The 275/55R20 designation contains specific measurements that directly impact how your vehicle handles, rides, and performs.
Each number in the 275/55R20 code tells a different part of the story. The 275 indicates the tire's width in millimeters measured at the widest point. The 55 represents the aspect ratio—meaning the sidewall height equals 55% of the tire's width. This qualifies as a "low profile" tire since any aspect ratio below 70% falls into this category. The R designates radial construction, which is standard for modern tires. The 20 specifies the rim diameter in inches.
For mounting flexibility, these tires work with wheels ranging from 7.5 to 9.5 inches wide. This range accommodates both factory and aftermarket wheel options.
Converting the metric specifications reveals the tire's true size. A 275/55R20 measures 31.9 inches in overall diameter. The section width spans 10.8 inches, while the sidewall height measures 5.95 inches. The radius extends 15.95 inches from the wheel center to the tread edge.
The circumference measures 100.25 inches—a crucial measurement for speedometer calibration and fuel economy calculations. This figure determines exactly how far your vehicle travels with each complete wheel rotation.
Understanding revolutions per mile helps predict how tire changes affect your vehicle's systems. A 275/55R20 tire completes 632 revolutions per mile (393 per kilometer). When you switch to a different size like 285/55R20, which makes 623.58 revolutions per mile, your speedometer reads differently—showing 60 mph when you're actually traveling 60.81 mph.
Tire size also affects engine RPM. With a 3.73 final drive ratio at 65 mph, your engine turns approximately 2,554 RPM with 275/55R20 tires. This relationship between tire dimensions and engine speed influences fuel consumption and overall performance.
The 275/55R20 provides better fuel efficiency than taller options like the 275/60R20, thanks to its smaller diameter and lower rolling resistance.
