Do you ever look closely at your vehicle's tires and wonder what all those numbers on the sidewall mean? Understanding these numbers is important for maintaining your tires properly and ensuring a safe driving experience. At Jeff Wyler Springfield Toyota in Springfield, OH, our knowledgeable service team is here to help you understand your tire sidewall.

Tire Width

The first number on your tire sidewall is the tire width in millimeters. This measures the widest point of the tire from sidewall to sidewall. Wider tires generally offer more grip and better handling. If you frequently drive on winding roads around London, OH, having tires with proper width is crucial.

Aspect Ratio

Following the tire width, you can see a slash and another two-digit number. This is the aspect ratio, which compares the tire's height to its width as a percentage. A lower aspect ratio means a shorter sidewall, which provides quicker steering response and better cornering around Dayton.

Tire Construction

Next, there will be a letter - R, D, or B. In most cases, it will be R, which stands for radial. Radial tires have plies (internal layers) that radiate from the center, perpendicular to the tread. This construction provides a smoother ride and longer tread life around Fairborn.

Wheel Diameter

The two-digit number after the tire construction letter indicates your wheel diameter in inches. This is the size of the wheel from one end to the other. Your tire and wheel diameter must match for proper fit and safety. When it's time for new tires, visit our service center, and our experts will ensure you get the right size for your vehicle.

Load Index and Speed Rating

The last numbers on your sidewall are the load index and speed rating. The load index is a two or three-digit number corresponding to the tire's maximum load-carrying capacity. The higher the number, the more weight the tire can support. Speed rating is a letter and relates to the maximum speed a tire can safely maintain.
