Have you ever looked closely at the sidewall of your vehicle's tires and wondered what all those numbers and letters mean? Understanding these codes is important for selecting the right tires for your car or truck. Let's break down the meaning of each marking so you'll be well-informed the next time you need new tires in Fairfield, OH.
Tire Width
The first number on the tire sidewall indicates the width of the tire in millimeters. This is measured from sidewall to sidewall. Wider tires generally provide more grip, but the ideal width depends on your specific vehicle.
Aspect Ratio
After the slash mark, you'll see a two-digit number that represents the tire's aspect ratio. This is the height of the sidewall as a percentage of the width. A lower aspect ratio means a shorter sidewall, which provides crisp handling but a firmer ride. Higher aspect ratios offer a softer ride and better traction in snowy conditions. Many Cincinnati drivers prefer a balanced aspect ratio for a smooth, comfortable ride.
Construction
Next, you'll see a letter indicating the tire's internal construction. "R" stands for radial, which is the industry standard for most passenger vehicles. Radial tires provide a good balance of ride comfort and durability.

Wheel Diameter

Load Index and Speed Rating
The tire's load index and speed rating are the final numbers on the sidewall, usually separated by a space. The load index is a numerical code specifying how much weight the tire can support when properly inflated. The speed rating letter denotes the maximum speed the tire is engineered to sustain over time.
Find the Right Tires for Your Vehicle
Now that you know how to decode the markings on your tire sidewall, you'll be better prepared to choose replacements that match your vehicle's specifications. It's also crucial to maintain proper tire pressure and rotate your tires regularly to ensure even wear and optimal performance.
