Have you ever looked at the side of your vehicle's tires and wondered what all those numbers mean? While they seem like random digits, the numbers on a tire's sidewall provide important information about its size, construction, and performance capabilities. Understanding these numbers can help you choose the right tires for your vehicle and driving needs. Drivers in the Fort Thomas, KY, area can rely on the knowledgeable service technicians at Jeff Wyler Chrysler Dodge Jeep® RAM of Ft Thomas's service center to help explain tire specs and assist with all your tire maintenance and replacement needs.
Tire Size Specifications
The most prominent numbers on a tire's sidewall indicate the tire's size. The first number specifies the tire's width in millimeters from sidewall to sidewall. Drivers around Highland Heights, KY, and surrounding areas commonly see tire widths ranging from 175 to 325 millimeters.
The second number, the aspect ratio, is the height of the sidewall expressed as a percentage of the width. A lower aspect ratio means a shorter sidewall, generally providing sportier handling but a firmer ride.
Following the tire width and aspect ratio is a letter indicating the tire's internal construction, usually "R" for radial tires, which are the most common type of tires today.
The final number is the diameter of the wheel rim in inches. So, a tire sized P215/60R16 has a width of 215 millimeters, an aspect ratio of 60%, is a radial tire, and fits a 16-inch wheel. Proper tire sizing is critical for vehicle safety, performance, and fuel efficiency.
Tire Type and Speed Rating
In addition to the size numbers, tire sidewalls include letters indicating the tire's type and speed rating. Drivers around Newport, KY, often choose between all-season (AS), summer/performance, and winter tires depending on their vehicle and typical driving conditions. The speed rating, ranging from L (75 mph) to Y (186 mph), specifies the tire's maximum speed capability when properly inflated and not overloaded. It's important to select tires with a speed rating that meets or exceeds your vehicle manufacturer's recommendations.
