Reading a car tire involves understanding the series of numbers and letters printed on the sidewall. Here’s how to break it down:
- Tire Size:
Typically, you’ll see something like this: P215/60R16 95H.- P: This letter indicates the type of tire. “P” means it’s a passenger vehicle tire. If you see “LT,” it means “Light Truck” tire.
- 215: This is the tire width in millimeters (from sidewall to sidewall).
- 60: This is the aspect ratio, representing the height of the tire sidewall as a percentage of the tire’s width. In this case, the sidewall height is 60% of 215mm.
- R: This indicates that the tire has a radial construction (most modern tires are radial).
- 16: This is the diameter of the wheel (in inches) that the tire is designed to fit.
- Load Index:
- 95: This is the load index, which tells you the maximum weight the tire can support. Each number corresponds to a specific weight; in this case, 95 equals 1,521 pounds (690 kg) per tire.
- Speed Rating:
- H: The letter at the end indicates the speed rating, which tells you the maximum speed the tire can handle. “H” means it can safely go up to 130 mph (210 km/h).
- Additional Information:
- You may also see markings like M+S (Mud and Snow) indicating a tire’s ability to handle mud or snow, or DOT for compliance with U.S. Department of Transportation standards.
By understanding these markings, you can interpret the tire’s specifications and ensure you’re using the right type for your vehicle and driving needs.
Understanding How to Read a Tire is crucial when selecting the right one for your vehicle. Let’s break down tire markings like 205/55R16 91V:
- Tire Width (205):
Indicates the tire’s width in millimeters. In this example, the tire is 205 mm wide. Wider tires usually offer better grip. - Aspect Ratio (55):
Represents the sidewall height as a percentage of the tire’s width. Here, it’s 55%, meaning shorter sidewalls for better handling but reduced comfort. - Construction (R):
“R” stands for radial construction, the most common type. Radial tires are known for their durability and smooth performance. - Rim Diameter (16):
This is the wheel diameter, measured in inches, that the tire fits. In this case, it’s designed for a 16-inch rim. - Load Index (91):
Shows the maximum weight each tire can carry. For example, a “91” rating means it can hold up to 615 kg. - Speed Rating (V):
Denotes the maximum speed the tire can handle, with “V” indicating a limit of 240 km/h (149 mph).
