The typical OE tire size for most 2015 Equinox models is P245/65R17 on 17-inch wheels. If your vehicle has 18-inch wheels, the common size is P245/60R18. Always confirm with the door placard or owner's manual for your specific trim and wheel setup.
Common tire sizes by wheel diameter
The Equinox was offered with two main wheel options in 2015. Here are the standard sizes you’re likely to encounter based on wheel diameter.
- P245/65R17 — for 17-inch wheels (common on base and many trims)
- P245/60R18 — for 18-inch wheels (optional/upgrade trims)
These sizes reflect the most frequently installed OE configurations. Individual vehicles may differ based on the exact trim package and regional market, so verify on the vehicle’s placard.
How to verify the correct tire size
To ensure you’re buying the right tires, check the sticker on the driver’s door jamb, the owner’s manual, or the tire information placard in your glove box. You can also confirm via your vehicle’s VIN-based spec sheet from a Chevrolet dealer.
Notes on tires and safety
Using the wrong tire size can affect handling, speedometer accuracy, and ABS/traction control performance. If you’re replacing tires, it's best to match the OE size and to replace all four tires at the same time to maintain even traction.
Summary
For a 2015 Chevy Equinox, the typical tire size is P245/65R17 on 17-inch wheels, with P245/60R18 on models equipped with 18-inch wheels. Always verify the exact size for your specific trim and wheel setup using the door placard or manual.
