What 255/55R20 tires means
The size code breaks down into exact measurements. The 255 is the section width in millimeters (about 10.04 inches). The 55 is the aspect ratio, meaning the sidewall height is 55% of that width, which works out to roughly 140.2 mm (5.52 inches). The R means radial construction, and 20 is the wheel diameter in inches.
Add two sidewalls to the rim and you get an overall tire diameter of about 31.04 inches, turning roughly 650 revolutions per mile. Those numbers matter: overall diameter determines speedometer accuracy and how the tire clears your fenders and suspension, while sidewall height influences ride comfort and cornering feel. Staying close to your factory diameter keeps your speedometer honest and your fitment safe.
Vehicles & uses
This is a popular 20-inch fitment for crossovers, SUVs, and light trucks. Sources show it offered across highway-terrain, all-season touring, and all-terrain categories aimed at passenger, CUV, and light-truck use. Because it spans comfort-focused touring designs through more rugged all-terrain patterns, buyers range from commuters wanting a quiet ride to owners who venture onto gravel and light trails. Always confirm the size against the placard on your driver's door jamb before buying.

How to choose
Start with season. All-season tires balance year-round grip; dedicated winter tires excel in snow and ice; summer tires prioritize warm-weather traction and handling. Match the choice to your climate.
Check the UTQG treadwear grade to compare relative tread longevity within a brand, and pair it with the mileage warranty for a fuller picture of expected life. Finally, respect the load index and speed rating stamped after the size (for example the 107 and 110 load figures and H, V, or Y speed letters seen in this size): they must meet or exceed your vehicle's requirements.
