As a car owner in Cincinnati, it's important to understand the various numbers and codes printed on your tire sidewalls. These digits provide crucial information about your tires' size, construction, and performance capabilities. Knowing how to read tire numbers can help you make informed decisions when it's time for replacements or upgrades at your local service center.
Tire Width
The first three digits on a tire sidewall represent the tire width in millimeters. For example, if you see "225" as the first number, that means your tire is 225 millimeters wide from sidewall to sidewall. Drivers in Fairfield should note that wider tires generally provide more grip and stability, while narrower tires are often more fuel-efficient.
Aspect Ratio
Following the tire width, you'll see a slash and then two more digits. This is the aspect ratio, which denotes the height of the tire's sidewall as a percentage of its width. A "70" means the sidewall height is 70% of the tire width. Lower aspect ratios, common on performance vehicles in Norwood, create a stiffer ride but sharper handling.
Construction Type
Adjacent to the aspect ratio, you'll find a letter, usually "R", indicating the tire's construction. "R" stands for radial, meaning the tire's layers run radially across the tire. Radial tires are the most common type for passenger vehicles in Springdale due to their durability, fuel efficiency, and smooth ride.
Wheel Diameter
The last two digits on the sidewall represent your wheel's diameter in inches. If you see "18", your tire is designed to fit an 18-inch wheel. Covington drivers should ensure they choose tires that match their wheels' diameter for proper fit and performance.
Load Index & Speed Rating
Following the wheel diameter, you may see additional digits and letters. These represent the tire's load index and speed rating. Load index indicates the maximum weight a tire can support when properly inflated, while speed rating specifies the tire's maximum safe speed. Always choose tires with load and speed ratings appropriate for your vehicle and driving style.
