As a driver in the Batavia, OH, area, it's important to understand the various numbers and codes printed on the sidewall of your vehicle's tires. These numbers provide essential information about the tire's size, construction, and performance capabilities. At Jeff Wyler Eastgate Nissan, we help decode these numbers so you can make informed decisions about your tires.
Tire Width
The first number on a tire sidewall indicates the tire's width in millimeters from sidewall to sidewall. Technicians take this measurement at the widest point of the tire. Wider tires typically provide more grip and handling, while narrower tires tend to be more fuel-efficient near Hillsboro, OH.
Aspect Ratio
Following the tire width, you will notice a slash and another two-digit number. This number represents the tire's aspect ratio, which is the height of the sidewall expressed as a percentage of the tire's width. A lower aspect ratio means a shorter sidewall, improving handling and responsiveness.
Construction Type
The next letter on the tire sidewall indicates the tire's internal construction. The most common types are "R" for radial construction and "D" for diagonal or bias-ply construction. Radial tires are the most popular choice for modern vehicles, offering better fuel efficiency, longer tread life, and improved handling compared to bias-ply tires.
Wheel Diameter
The number following the construction type represents the wheel diameter in inches. This measurement corresponds to the size of the wheel that the tire fits. Ensuring you choose tires with the correct wheel diameter is essential for proper fitment and performance.
Load Index and Speed Rating
The final numbers on the tire sidewall indicate the tire's load index and speed rating near Milford, OH. The load index is a numerical code corresponding to the maximum weight the tire can support when properly inflated. The speed rating, represented by a letter, indicates the maximum speed at which the tire can safely operate.
