How can I tell what size tires are on my car?
Knowing the correct tire size for your vehicle is essential for maintaining its performance, safety, and fuel efficiency. Fortunately, there are several easy ways to determine the tire size on your car. In this article, we'll guide you through the process step-by-step.
Locating the Tire Size Information
The easiest way to find your car's tire size is to look for the information on the driver's side door jamb sticker. This sticker, also known as the "tire information placard," will list the recommended tire size for your vehicle. You can also find the tire size information in your owner's manual or on the sidewall of your current tires.
Understanding Tire Size Codes
Tire size codes can seem confusing at first, but they're actually quite straightforward. A typical tire size code looks something like this: P215/55R17. Here's what each part of the code means:
- P - Indicates a passenger vehicle tire
- 215 - The tire's width in millimeters
- 55 - The aspect ratio, which is the ratio of the tire's sidewall height to its tread width
- R - Indicates a radial tire construction
- 17 - The wheel diameter in inches that the tire is designed to fit
Knowing how to interpret this code will help you ensure you're getting the right replacement tires for your car.
Checking the Tire Sidewall
If you can't find the tire size information in your owner's manual or on the door jamb sticker, you can also check the sidewall of your current tires. The tire size will be clearly printed there, usually in a format similar to the one described above.
Consulting a Tire Size Calculator
If you're still unsure about your tire size, you can use an online tire size calculator. These tools allow you to input your vehicle's make, model, and year, and they'll provide the recommended tire size for your car.
Determining the correct tire size for your vehicle is an important step in maintaining its performance and safety. By following the steps outlined in this article, you can easily identify the right tires for your car.
How do I read my car tire size?
Here's what each one means.
- A: TIRE TYPE. The first letter in the code tells you what class of tire it is.
- B: TIRE WIDTH. The three-digit number following the letter is the tire's width (from side to side, looking at the tire head-on) in millimeters.
- C: ASPECT RATIO.
- D:
- E: WHEEL DIAMETER.
- F: LOAD INDEX.
- G: SPEED RATING.
Where do I find my tire size on my car?
You can find your vehicle's tire size on the Tire Label on the B-pillar or edge of the driver's door. The Tire Label shows the original size of the tires, the recommended inflation pressure, and the maximum weight the vehicle can carry.
Can I put 60 tires instead of 65?
Similarly, we only recommend changing the aspect ratio by 5% either side of your cars preferred size. For example, a car designed to take a 60 aspect ratio tire could also fit a 55 or 65 aspect ratio. In winter it is very common to 'downsize' tires – this is making the width slightly smaller.
How to determine the size of a tire?
To calculate the overall diameter of a tire, the sidewall height must be multiplied by 2 (remembering that the tire diameter is made up of 2 sidewalls, the one above the wheel and the one below the wheel touching the ground) and add the diameter of the wheel.
Can I use 65 tires instead of 60?
Similarly, we only recommend changing the aspect ratio by 5% either side of your cars preferred size. For example, a car designed to take a 60 aspect ratio tire could also fit a 55 or 65 aspect ratio. In winter it is very common to 'downsize' tires – this is making the width slightly smaller.
Can I use 225 tires instead of 245?
If you reside in a place where winters are harsh, 225 tires can be a safer option. 245 tires might be a better option in milder regions or for high-performance driving.
Can I look up tire size by VIN number?
Several resources can help decode VINs for tire size information: Manufacturer Websites: Many car manufacturers offer VIN lookup tools on their websites. Online VIN Decoders: Various free and paid services can decode VINs and provide vehicle specifications.
Which tire is taller a 65 or 70?
The second number in a tire size refers to the height of the sidewall of a tire. A larger number means a taller sidewall. Assuming the 255/65's are stock size for your car, you should have no problems moving into a 255/70. The difference between the two are negligable.
How do I know my tire size number?
Reading Your Tires
- Tire Class – “P” The first character(s) in a tire size designate the tire's class.
- Section Width – “205” A metric tire's section width is measured in millimeters.
- Aspect Ratio – “65”
- Tire Construction – “R”
- Wheel Diameter – “16”
- Diameter – “35”
- Tire Width – “1250”
- Tire Construction – “R”
Which tire is taller, 60 or 65?
The main difference between 60 and 65 tires lies in their aspect ratios, with 60 tires having a lower sidewall height compared to 65 tires. As a result, 60 tires provide better handling and a sportier feel, while 65 tires offer a more comfortable ride and better impact absorption.
