As a driver in Springfield, OH, it's important to understand the information printed on your vehicle's tires. The numbers and letters on the sidewall of your tires provide important details about the tire's size, construction, and performance capabilities. Knowing what these numbers mean can help you choose the right tires for your vehicle and driving needs.
Decoding the Numbers on Your Tire Sidewall
The first number on the tire sidewall indicates the tire width in millimeters. For example, if the number is 225, this means the tire is 225 millimeters wide from sidewall to sidewall.
The next number is the aspect ratio, which is the height of the tire sidewall expressed as a percentage of the tire width. A lower aspect ratio means a shorter sidewall, which generally provides better handling but a firmer ride. Drivers in the Dayton area who want a smooth, comfortable ride may prefer tires with a higher aspect ratio.
After the aspect ratio, you'll see a letter - either "R" for radial construction or "D" for diagonal construction. The vast majority of passenger tires today are radial tires. Following this is the wheel diameter, which is the size of the wheel from one end to the other, expressed in inches.
The load index and speed rating are also important numbers on the tire sidewall. The load index is a number that corresponds to the maximum weight a tire can support when properly inflated. Beavercreek drivers who carry heavy loads or tow trailers will need tires with a high load index. The speed rating, usually a letter, indicates the maximum speed at which the tire can safely operate.
