Have you ever looked closely at the sidewall of your vehicle's tires and wondered what all those numbers and letters mean? While they may seem like random gibberish at first glance, each marking actually provides important information about the tire's size, construction, performance capabilities and more. It's helpful to understand how to read tire sidewalls so you can maintain your tires properly and know when it's time for replacements.
Decoding the Numbers on Your Tire Sidewalls
Tire Width
Car owners from Springdale spotting the first number on a tire sidewall will get information on tire width in millimeters from sidewall to sidewall. Passenger vehicle tires typically range from 175 to 325 millimeters wide. If you're looking for new tires around Cincinnati, be sure to match this width number for proper fitment on your wheels.
Aspect Ratio
After the slash mark, the next number is the aspect ratio. This is the height of the sidewall expressed as a percentage of the tire width. A smaller aspect ratio means a shorter sidewall and sportier handling, while a taller sidewall provides a smoother ride. Maintaining the correct aspect ratio is crucial for optimal performance driving around Hamilton.
Internal Construction
The letter after the aspect ratio denotes the tire's internal construction. "R" stands for radial, which is the industry standard for modern tires. Radial tires have fabric-reinforced rubber that runs perpendicular to the direction of travel for durability and ride comfort. If you need a tire inspection in Fairfield, one of our technicians can check for any internal damage.
Wheel Diameter
The last number in the sequence is the wheel diameter in inches. This is the size of the wheel from one end to the other that the tire is intended to fit. Your replacement tires need to match this wheel diameter to be compatible with your vehicle. We're a trusted tire resource for the Tri County, OH area, and our experts can help you find the right diameter tires.
Load Index and Speed Rating
The tire's load index and speed rating are the numbers and letters that follow the main size markings. The load index is a number that corresponds to the tire's maximum weight capacity when properly inflated. The speed rating letter denotes the maximum speed capability of the tire. It's important not to exceed these limits to prevent tire failure traveling to various Tri County, OH destinations.
