How to Tell the Size of Your Tires
In this section, we will provide a step-by-step guide on how to tell the size of your tires. Follow these simple steps to ensure you have the correct information:
1. Locate the Tire Information Placard: The tire information placard is usually located on the driver’s side doorjamb, inside the fuel filler door, or on the inside of the trunk lid. It provides information about your vehicle’s recommended tire size, inflation pressure, and other important details.
2. Check the Tire Sidewall: The tire sidewall provides the tire size information. Look for the following details:
- Tire Size: This is the first set of numbers on the sidewall, usually in the format “P215/65R17” (P = tire type, 215 = width, 65 = aspect ratio, and 17 = rim size).
- Tire Width: This is the width of the tire in millimeters, usually the first set of numbers.
- Aspect Ratio: This is the ratio of the tire’s height to its width, usually expressed as a percentage.
- Rim Size: This is the diameter of the wheel rim in inches, usually the last set of numbers.
3. Check the Tire Label: Some tires have a label on the tire itself, which provides the tire size information. Look for the label on the tire’s sidewall or on the inside of the tire.
By following these simple steps, you can easily determine the size of your tires and ensure you have the correct information for your vehicle. Remember, proper tire size is crucial for the safety, performance, and fuel efficiency of your vehicle.

How do I read the tire size on my vehicle?
You can usually find the tire size on the tire information placard, which is typically located on the driver’s side doorjamb, inside the fuel filler door, or on the inside of the trunk lid. The placard will display the recommended tire size, speed rating, and inflation pressure for your vehicle.
What is the significance of the aspect ratio?
The aspect ratio is the ratio of the tire’s height to its width. A lower aspect ratio means a shorter sidewall, which can improve handling and braking, but may also increase the risk of tire damage. A higher aspect ratio means a longer sidewall, which can provide a smoother ride and better traction, but may also affect handling.
Can I use a tire with a different size than recommended?
No, it’s not recommended to use a tire with a different size than recommended by the manufacturer. Using a tire that is too small or too large can affect the vehicle’s handling, braking, and overall performance. It can also void the warranty and increase the risk of tire failure.
How do I know if my tires are underinflated?
You can check your tire pressure by using a tire pressure gauge. Compare the reading to the recommended pressure listed on the tire information placard or in your vehicle’s owner’s manual. If the pressure is lower than recommended, your tires are underinflated. It’s also a good idea to check your tire pressure regularly, as underinflation can lead to reduced fuel efficiency, uneven tire wear, and increased risk of tire failure.
