Relevant Specifications

  1. Aspect Ratio: The aspect ratio is the ratio of the sidewall height to the tread width. For the 275/65r20 tire, the aspect ratio is 65%, meaning the sidewall height is 65% of the tread width.
  2. Load Index: The load index is a numerical code that indicates the maximum load-carrying capacity of the tire. The specific load index for the 275/65r20 tire size will depend on the tire manufacturer and model.
  3. Speed Rating: The speed rating is a letter code that indicates the maximum speed the tire can safely sustain for an extended period. Like the load index, the speed rating for the 275/65r20 tire size will vary based on the tire manufacturer and model.
  4. Tire Construction: Tire construction refers to the type of internal structure used to build the tire. The 275/65r20 tire size typically features radial construction, with layers of fabric or steel belts running radially across the tire, from bead to bead. This design offers better traction, handling, and ride comfort than bias-ply tires.

 

What Does 275/65R20 Mean?

The term “275/65R20” refers to the size and specifications of a tire. Here’s a breakdown of what each part of the designation means:

  • 275: This number represents the width of the tire in millimeters. In this case, the tire is 275 millimeters wide from sidewall to sidewall.
  • 65: This number indicates the aspect ratio, which is the ratio of the tire’s sidewall height to its width. In this example, the aspect ratio is 65, meaning the sidewall height is 65% of the tire’s width.
  • R: This letter stands for “radial,” which is the most common type of tire construction. Radial tires have ply cords that run perpendicular to the direction of travel.
  • 20: This number represents the diameter of the wheel, in inches, on which the tire is designed to fit.

So, in summary, a tire with the designation 275/65R20 is a radial tire that is 275 millimeters wide, with a sidewall height that is 65% of the width, and it is designed to fit a 20-inch wheel.
