The tire sidewall contains valuable information to help you select the right tires. Tire size, load index, and speed rating indicate the tire's specifications. Treadwear, traction, and temperature ratings provide insight into the tire's performance. The DOT identification number tracks tire age and recalls. Our experts at Fast New and Used Tire Service can decode all the tire sidewall markings to ensure you get the perfect tires for your vehicle and driving needs.

At Fast New and Used Tire Service, we understand that the complex array of numbers, letters, and symbols on a tire's sidewall can be confusing for many drivers. However, these tire sidewall markings contain a wealth of valuable information that can help you make an informed decision when selecting the right tires for your vehicle. As your trusted tire experts, let us guide you through the key elements of tire sidewall markings and what they mean

Tire Size

The tire size is typically displayed in the format "P215/65R15" or "215/65R15". The first number (215 in this example) represents the tire's width in millimeters. The second number (65) is the aspect ratio, which is the ratio of the tire's sidewall height to its tread width. The "R" stands for radial, the most common tire construction. The final number (15) indicates the wheel diameter in inches that the tire is designed to fit. Our team at Fast New and Used Tire Service can help you ensure the correct tire size for your vehicle.

Load Index and Speed Rating

These two numbers work together to indicate the tire's load-carrying capacity and maximum safe speed. The load index is a numerical code that corresponds to a specific weight limit. The speed rating is a letter code (e.g., "S", "T", "H", "V", "W", "Y") that denotes the tire's maximum sustained speed capability. Our experts will help you select tires with the appropriate load index and speed rating for your driving needs.

Treadwear, Traction, and Temperature Ratings

These ratings, often referred to as the "Uniform Tire Quality Grading" (UTQG) system, provide a relative assessment of the tire's expected treadwear life, traction performance, and temperature resistance. The treadwear rating is a numerical value, while the traction and temperature ratings are letter grades. We'll explain these ratings to you in detail to help you choose the best tires for your driving conditions.

DOT Tire Identification Number

The DOT (Department of Transportation) tire identification number is a unique code that provides information about the tire's manufacture date, plant of origin, and other details. This number is essential for tracking tire recalls and determining the age of your tires. Our team at Fast New and Used Tire Service can help you interpret this information and ensure you're using safe, up-to-date tires.

Other Markings

Tire sidewalls may also include additional information, such as the tire's construction type (radial, bias-ply, etc.), the presence of special features (run-flat, self-sealing, etc.), and even the manufacturer's logo or branding. We'll help you understand all the markings on your tires to ensure they meet your specific needs.

Our goal therefore is to empower you with the knowledge to make informed decisions about your tire purchases in our shop. By familiarizing yourself with the meanings of these tire sidewall markings, you can be confident that you're selecting tires that match your vehicle's specifications and your driving requirements.
