Chevrolet Equinox Bolt Pattern, Wheel & Tire Sizes
TL;DR
Bolt pattern changed twice across Equinox history and the Equinox EV uses a different pattern altogether than the gas Equinox - always match wheels to your exact generation, not just the nameplate.
Why there is no single Equinox bolt pattern
Chevrolet has built the Equinox on at least three different chassis generations plus a separate electric model, and the wheel hub specification changed with the platform. Fitting a wheel meant for the wrong generation - even one that looks close - will not seat correctly on the hub.
Bolt pattern, centre bore and thread by generation
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| 1st gen (2005-2009) | 5x115 mm (5x4.53 in) | 70.3 mm | M12 x 1.5 | 16-17 in | 235/65R16, 235/60R17 |
| 2nd gen (2010-2017) | 5x120 mm (5x4.72 in) | 66.9 mm | M14 x 1.5 | 17-20 in | 225/65R17, 235/60R17, 235/55R18, 235/55R19, 255/40R20 |
| 3rd gen (2018-2023) | 5x115 mm (5x4.53 in) | 70.3 mm | M12 x 1.5 | 17-19 in | 225/65R17, 225/60R18, 235/50R19 |
| 3rd gen refresh (2024-2026, gas) | 5x115 mm (multiple listings group this refresh with 2017-2025 fitments) | Reported as 70.3 mm in line with the prior generation - not independently re-verified for every 2024-2026 trim | M12 x 1.5 | 17-19 in | 225/65R17, 235/55R18, 235/55R19 |
| Equinox EV (2024-2026, separate electric model) | 6x120 mm | 66.9 mm | M14 x 1.5 | 19-21 in | Up to 275/40R21 on RS trim; smaller sizes fitted on lower trims - confirm on your door placard |
Sources disagree slightly on tire sizes
Aggregator databases show minor variation in the exact 18-19 inch tire sizes listed for 2018-2020 versus 2021-2023 model years (some list 225/60R18 and 235/50R19, others list 235/55R18 and 235/55R19 for similar trims). Both are plausible factory fitments depending on trim package, so treat the 18-19 inch figures as a range rather than one fixed number.
Always confirm on your own vehicle
Do not rely on a generic chart alone. The authoritative source for your exact vehicle is the tire and loading information placard on the driver-door jamb (or door pillar), the sidewall markings on your current tires and wheels, your owner's manual, and - for towing-related wheel/tire load ratings - the manufacturer's towing guide. These reflect the exact trim, wheel option and market build of your specific Equinox.

Frequently asked questions
Did the Chevrolet Equinox bolt pattern ever change?
Yes. The first generation (2005-2009) and the third generation onward (2018-2026 gas models) use 5x115 mm, but the second generation (2010-2017) switched to 5x120 mm. The separate battery-electric Equinox EV (2024-2026) uses yet another pattern, 6x120 mm. Always check your specific model year and whether your vehicle is the gas Equinox or the Equinox EV before buying wheels.
Is the centre bore the same across generations?
No. Reported centre bore is about 70.3 mm for the 5x115 mm generations (2005-2009 and 2018-2023, with the 2024-2026 refresh expected to match) and about 66.9 mm for the 2010-2017 generation and for the Equinox EV. Hub-centric spacers may be needed if an aftermarket wheel's bore does not match your hub.
What stud thread size does the Equinox use for lug nuts?
Vehicles with the 5x115 mm pattern (2005-2009, 2018-2026 gas models) use M12 x 1.5 studs. Vehicles with the 5x120 mm pattern (2010-2017) and the Equinox EV's 6x120 mm pattern use M14 x 1.5 studs. Using the wrong thread size can cross-thread lug nuts or leave them under-torqued.
What is the factory tire size on my Equinox?
It depends on trim and wheel option, ranging roughly from 225/65R17 on base wheels up to 235/50R19 or 275/40R21 (Equinox EV RS) on the largest factory wheel option. Read the exact size directly off your driver-door placard or your current tire sidewall - that reflects your specific build, not just the model year.
