What 285/55R20 tires means
The size code breaks down into exact measurements you can use to compare fitment and ride. Here's what each number represents:
- 285 — section width of 285 mm (about 11.22 in), the tire's width at its widest point.
- 55 — aspect ratio, meaning the sidewall height is 55% of the section width, which works out to roughly 156.8 mm (6.17 in).
- R20 — radial construction on a 20-inch rim.
Add it up and you get an overall tire diameter near 32.34 inches, turning about 624 revolutions per mile. Those numbers matter: overall diameter affects your speedometer accuracy and how much fender clearance you need, while the 6.17-inch sidewall influences ride comfort and bump absorption. Staying close to your original diameter keeps your speedometer reading true.
Vehicles & uses
This is a popular truck and SUV size. Fitment guides commonly describe 285/55R20 as an all-terrain and truck/SUV tire size, well suited to pickups, full-size SUVs, and crossovers that run 20-inch wheels. Because the choices here lean heavily toward all-terrain, rugged-terrain, and mud-terrain patterns, it's a size that serves owners who split time between daily highway driving and gravel, dirt, or light trail use. Always confirm the size against the placard on your driver's door jamb before ordering.

How to choose
Season
Match the tire to your climate. All-season tires balance year-round driving; summer tires favor dry and wet grip in warm weather; winter tires are built for snow and cold. Many all-terrain patterns in this size carry three-peak mountain snowflake capability, but confirm on the individual tire page before you rely on it.
Treadwear & UTQG
The UTQG rating covers treadwear, traction, and temperature. A higher treadwear grade generally suggests longer expected tread life, but compare within similar tire types since grading is relative to each manufacturer's testing.
Load index & speed rating
The load index and speed rating stamped on the sidewall must meet or exceed your vehicle's requirements — especially important on trucks and SUVs that tow or haul. Verify both against your door placard.
Warranty
Warranty coverage varies by maker and model. Review the specific terms on the tire you're considering.
