Have you ever looked closely at the side of your vehicle's tires and wondered what all those numbers mean? While they may seem like random digits, the numbers on your tire sidewall provide important information about the tire's size, construction, and performance capabilities. Here's a quick overview of how to decode that cryptic tire code.

Tire Width
The first number in the tire size code indicates the tire's width in millimeters from sidewall to sidewall. Wider tires generally offer more grip and improved handling, so performance cars often feature wider wheels and tires. Drivers around Columbus, Ohio, can choose from various tire widths to suit their driving preferences and vehicle type.
Aspect Ratio
Following the tire width, you'll see a slash and a two-digit number. This number is the aspect ratio, which compares the tire's cross-section height to its width as a percentage. A lower aspect ratio means a shorter sidewall and stiffer ride, while a taller sidewall provides more cushioning. Many Lancaster, Ohio, drivers prefer a moderate aspect ratio for a balance of comfort and cornering performance.
Wheel Diameter
The next number in the sequence indicates the diameter of the wheel that the tire is designed to fit, measured in inches. Tires and wheels must match the diameters exactly. Often, changing wheel diameter also requires changing tires to maintain proper inflation pressure and load capacity. Upsizing wheels has become popular for Pickerington auto enthusiasts seeking a sporty look.
Load Index & Speed Rating
The tire's load index and speed rating are usually the last figures printed on the sidewall. The load index is a number that corresponds to the maximum weight the tire can support when properly inflated. Speed ratings range from L (75 mph) to Y (186 mph)and indicate the tire's maximum safe speed when carrying the maximum load. Choosing tires with a load index and speed rating high enough for your vehicle and driving habits around Groveport and beyond is critical.
