Do you wonder what all those numbers on your tire's sidewall mean? While they may look like a random jumble of digits to the untrained eye, each conveys important information about your tires. As a driver in Batavia, it's crucial to understand what your tire's sidewall is telling you.
Tire Width
The first number on your tire's sidewall is the tire width in millimeters. This measures the widest point from one sidewall to the other. For example, if the number is 225, your tire is 225 millimeters wide. Drivers around Cincinnati should ensure they have the proper tire width for their specific vehicle make and model.
Aspect Ratio
The next number is the aspect ratio, the height of the tire's cross-section as a percentage of its width. A lower aspect ratio means a shorter sidewall, providing sharper handling but a firmer ride.
Construction
Following the aspect ratio, you will see a letter - either R or D. This indicates the tire's construction, with R standing for radial and D for diagonal or bias ply. The vast majority of today's tires are radial tires. If you are unsure, visit our service center to have our experts inspect your tires near Amelia, OH.
Wheel Diameter
The number after the construction letter is the wheel diameter, which is the size of the wheel from one end to the other. This is in inches, so a number like 18 means the tire is intended for an 18-inch wheel. Proper wheel diameter is essential for drivers around Mason, OH, who want a smooth, safe ride.
Load Index and Speed Rating
The last numbers on the sidewall are the load index and speed rating. The load index is a numerical code specifying the maximum weight the tire can support when properly inflated. The speed rating is a letter indicating the tire's maximum speed capability.
