Have you ever wondered what all those numbers on the side of your tires mean? Understanding the tire size information is important for ensuring you have the right tires for your vehicle. Let's take a closer look at how to read the numbers on your tire sidewall with this example: P225/60R16.
Tire Type
The first letter, in this case, "P," stands for the tire type. A "P" indicates the tire is for passenger vehicles. If you have a light truck, you may see "LT" instead. Some tires may not have a letter at all. In Fairfield, OH, you'll see a lot of passenger tires since most vehicles on the road are cars, minivans, crossovers, and SUVs.
Tire Width
The first three numbers after the tire type represent the width of the tire in millimeters from sidewall to sidewall. In our example, the width is 225 millimeters. Tire width can affect traction, handling, ride comfort, and appearance.
Aspect Ratio
After the forward slash, the next two numbers are the aspect ratio. This is the height of the sidewall expressed as a percentage of the tire width. In our P225/60R16 example, the sidewall height is 60 percent of the 225mm tire width. A lower aspect ratio means a shorter sidewall for improved handling, while a taller sidewall provides a smoother ride.
Construction Type
The "R" after the aspect ratio stands for radial construction. Radial tires are the most common type, with the internal plies running perpendicular to the direction of travel. This provides durability, even wear, and low rolling resistance for good fuel efficiency. You may occasionally see a "D" for bias-ply construction or "B" for belted tires on classic cars around Dayton.
Wheel Diameter
The final number is the wheel diameter in inches. This is the size of the wheel the tire is designed to fit. Our example tire is made of 16-inch wheels. It's crucial to match the tire size to the correct wheel size for proper fit and performance. Consult your owner's manual or tire information placard to determine the right size for your car.
