What 275/55R20 tires means
The 275/55R20 size code describes the tire's exact geometry. Reading it left to right:
- 275 — the section width in millimeters (275 mm, or about 10.83 inches) across the widest part of the tread.
- 55 — the aspect ratio, meaning the sidewall height is 55% of the section width. That works out to roughly 151.2 mm (about 5.95 inches) of sidewall.
- R — radial construction.
- 20 — the wheel (rim) diameter in inches.
Add two sidewalls to the rim and the overall tire diameter comes to about 31.91 inches, which rolls roughly 632 revolutions per mile. Those numbers matter to a buyer: overall diameter affects speedometer accuracy and clearance inside the wheel well, while the near-6-inch sidewall gives you a cushioned ride and some sidewall protection over rough roads. Staying within this size keeps your speedometer and any ground-clearance geometry close to how the vehicle was set up.

How to choose
Season: Summer tires prioritize dry and wet grip in warm weather; all-season tires balance year-round use; all-weather and winter tires add cold-weather and snow traction. Match this to your climate first.
Treadwear & UTQG: The UTQG treadwear grade, traction and temperature ratings help you compare longevity and grip between models — check each tire's printed grade.
Load index & speed rating: These follow the size (for example, common 275/55R20 ratings include 113 and 117 load with T, H and V speed symbols). Meet or exceed your vehicle's placard requirement — never go below it.
Warranty: Mileage warranties vary by model, so weigh the coverage against price when you compare options.
