If you’re trying to determine the right tire size for your Chevy Equinox but are unsure how to interpret the numbers on a tire, you’ve come to the right place.
This blog will cover everything you need to know about tires for Chevrolet models, including their width, speed ratings, wheel sizes, and more.
Let’s dive into the details.
What Size Tire Fits a Chevy Equinox?
Understanding Rim Size
For every vehicle, including the Chevy Equinox, the rim size determines the correct tire size. This is because the tire must fit perfectly around the rim. Think of it this way: when you’re shopping for a shirt, you choose one that fits your body. The same principle applies to choosing a tire.
When you know the measurements of your arms, shoulders, chest, and upper body, it’s easy for a tailor to design a perfectly fitting shirt. Similarly, for the Chevy Equinox, you’ll need to know the rim size—its width and diameter. These measurements should then be compared with the tire’s width and diameter to ensure compatibility.
To take it a step further, for vehicles like the Equinox, wheel sizes are not universal. They vary depending on the year, model, and trim level. This is why it’s essential to double-check the specifications for your specific Chevrolet.
For example, 2020 models typically have an 8-inch rim width and a 17-inch diameter. Let’s use this measurement as a reference. If your truck has different specifications, this example will still help you understand how to determine the correct tire size.
Once you’ve gathered this information, match it with the numbers on the tire. However, understanding tire numbers can be a bit of a headache for many car owners since they are coded rather than simple numbers.
Tire Size Example for a 2020 Chevy Equinox
Let’s use the 2020 Chevy Equinox as an example. Its recommended tire size is P225/65R17 102H. Here’s what these numbers mean:
- 225: This represents the tire’s width in millimeters (mm). A width of 225 mm fits an 8-inch rim. Generally, tires with widths between 225-235 mm are recommended for an 8-inch rim, though sizes as narrow as 215 mm or as wide as 245 mm may also fit.
- 65: This is the aspect ratio, indicating the height of the sidewall as a percentage of the tire’s width.
- R17: The “R” stands for radial construction, and 17 is the diameter of the rim in inches.
Once you confirm these measurements, you can match the tire size to your rim size.

Decoding the Speed Rating
The letter at the end of the tire size indicates the tire’s speed rating. In the example P225/65R17 102H, the letter H corresponds to a maximum speed of 130 mph. Since the Chevy Equinox’s top speed is around 120 mph, an “H” speed rating is a suitable match.
Always ensure that the tire’s speed rating exceeds or matches the maximum speed of your vehicle.
Key Takeaways
To determine the right tire size for your Chevy Equinox:
- Identify your rim size (width and diameter).
- Match the tire’s specifications (width and diameter) to the rim size.
- Verify the speed rating is appropriate for your model.
For the 2020 Chevrolet Equinox, the recommended tire size is P225/65R17 102H.
However, earlier models and different trims may require different sizes, such as 275/55R16, 235/65R17, or 195/80R16. Always consult your vehicle’s manual or a trusted tire dealer to confirm the best fit.
