Choosing the right tires for your vehicle is crucial for optimal performance, safety, and handling. Understanding tire size specifications is essential for making an informed decision. One common tire size you might encounter is 275/55R20. This guide will delve into the meaning of this tire size and provide you with a comprehensive overview.
What Does 275/55R20 Mean?
Each tire size designation contains a series of numbers and letters that provide valuable information about the tire’s dimensions and construction. Let’s break down the meaning of 275/55R20:
Tire Width
The first number, 275, represents the tire’s width in millimeters, measured from sidewall to sidewall. In this case, a 275mm width indicates a relatively wide tire.
Aspect Ratio
The second number, 55, is the aspect ratio, which expresses the ratio of the tire’s height to its width as a percentage. A 55 aspect ratio means the tire’s height is 55% of its width.
Construction
The letter “R” stands for radial, indicating the tire’s construction type. Radial tires are the most common type and feature cords that run radially from bead to bead, providing better handling and fuel efficiency.
Rim Diameter
The final number, 20, represents the rim diameter in inches. This is the size of the wheel the tire will be mounted on.

Decoding the Tire Size 275/55R20
Tire sizes are standardized using a specific code that provides valuable information about the tire’s dimensions, construction, and load capacity. The code 275/55R20 is no exception. Let’s break it down:
275: Section Width
The first number, 275, represents the tire’s section width in millimeters. This measurement indicates the width of the tire from sidewall to sidewall. A wider tire generally provides better grip and handling, but it can also increase rolling resistance and fuel consumption.
55: Aspect Ratio
The second number, 55, is the aspect ratio, expressed as a percentage. It represents the ratio of the tire’s height to its width. In this case, 55% means the tire’s sidewall height is 55% of its section width. A higher aspect ratio indicates a taller sidewall, which provides a smoother ride but can compromise handling and cornering ability.
R: Construction Type
The letter “R” stands for radial construction. This is the most common type of tire construction, where the cords that reinforce the tire are arranged radially around the bead. Radial tires offer better handling, fuel efficiency, and durability compared to bias-ply tires.
20: Rim Diameter
The final number, 20, represents the rim diameter in inches. This is the size of the wheel the tire will be mounted on. A larger rim diameter generally improves handling and performance, but it can also increase the overall cost of the tire.
