Collection: GMC Terrain OEM Wheels

The GMC Terrain is GMC's compact crossover, sitting below the Acadia in the brand's SUV lineup and built for buyers who want truck-inspired styling in a smaller, more efficient package. Since its 2010 launch, the Terrain has gone through three generations, with each major redesign bringing changes to the factory wheel specifications. The bolt pattern moved from 5x120 to 5x115 at the 2018 redesign, center bore and lug thread changed at the same time, and wheel diameter and width have shifted with nearly every generation and trim since. Because of that, generation and trim matter as much as bolt pattern when identifying the correct OEM wheel for a given Terrain. This guide covers the confirmed bolt pattern, center bore, and rim dimensions for each documented Terrain generation, along with how the factory wheel lineup has changed over time.

Quick Specs at a Glance

What Size Wheels Does the GMC Terrain Have?

It depends on generation and trim. The 1st-generation Terrain (2010-2017) started with a 17x7 wheel on base trims for 2010 through 2013, moving to a 17x7.5 wheel for 2014 through 2017. Mid and upper trims used an 18x7 wheel through 2012 and a 19x7 wheel from 2010 through 2015, both offered in chrome and machined finishes. The 2016 to 2017 facelift years carried an updated 18x7 wheel and a restyled 19x7 wheel with a different spoke design.

The 2nd-generation Terrain (2018-2024) starts with a 17x7 wheel on SL, SLE, and later AT4 trims. SLE and SLT trims used an 18x7 wheel at ET43 through the 2018 to 2021 pre-facelift years, and a 19x7.5 wheel at ET46 was used across SLT, Denali, and later Elevation trims from 2018 through 2022. The 2022 to 2024 facelift years continued with 18x7 and 19x7.5 wheels on AT4, Elevation, and Denali trims, though offset was not consistently confirmed for those later facelift wheels.

The redesigned 3rd-generation Terrain (2025-present) uses a 17x7.5 wheel on the Elevation and AT4 trims. The Denali trim steps up to a 19x7.5 wheel as standard, with a 20-inch wheel offered as a separate option on Denali. The exact width of that 20-inch wheel was not verified in the available source, so it is listed here by diameter only.

What Is the Bolt Pattern on the GMC Terrain?

The GMC Terrain used a 5x120 bolt pattern through its entire 1st generation, from 2010 through 2017. The redesigned 2nd generation switched to a 5x115 bolt pattern for 2018, and that same 5x115 pattern has carried through the D2XX Facelift years and into the redesigned 3rd-generation Terrain that arrived for 2025. A shared bolt pattern between the 2nd and 3rd generations does not by itself confirm that every wheel from one generation is a direct fit for the other, since wheel width, offset, and trim-specific design still vary.

GMC Terrain Center Bore and Offset

Center bore is documented at 66.9mm for the 1st-generation Terrain and 70.3mm for the 2nd generation, with the same 70.3mm center bore documented for the 3rd generation. Offset is confirmed at ET43 for the 2nd-generation 18x7 wheel and ET46 for the 2nd-generation 19x7.5 wheel, both figures tied to specific option codes on 2018 to 2022 production. Offset was not consistently verified for the 1st-generation Terrain or for the redesigned 3rd generation, so those figures are left out here rather than estimated.

Do GMC Terrain Wheels Interchange Between Generations?

Even where Terrain generations share basic hub specifications, their factory wheel dimensions can vary by generation, trim, and configuration. Shared bolt pattern and center bore alone do not establish direct-fit interchangeability. The 1st-generation Terrain uses a completely different bolt pattern, center bore, and lug thread than the 2nd and 3rd generations, so those wheels are not compatible across that divide. Within the 2nd and 3rd generations, the 5x115 bolt pattern and 70.3mm center bore are shared, but wheel width, offset, and trim-specific styling still differ enough that a wheel from one generation should not be assumed to be a direct match for another without confirming the complete dimensions.

About the GMC Terrain

The GMC Terrain is a compact crossover SUV positioned below the midsize Acadia in GMC's lineup. It's aimed at buyers who want GMC's truck-influenced styling and available all-wheel drive in a smaller footprint than the Acadia, and it typically competes for attention with the Honda CR-V and Toyota RAV4 in the compact crossover segment.

The Terrain launched for 2010 as a replacement for the GMC Envoy and the Pontiac Torrent, built on GM's Theta platform and offered in SLE and SLT trims before the Denali trim was added for 2013. A mid-cycle facelift arrived for 2016, bringing new front and rear styling along with updated wheel designs. General Motors redesigned the Terrain for 2018, moving it onto the D2XX platform, shrinking its footprint, and switching the bolt pattern from 5x120 to 5x115. A facelift for 2022 updated styling and trim names, adding the AT4 and Elevation trims. GMC introduced a completely redesigned 3rd-generation Terrain for 2025, launching with the Elevation trim only before adding the AT4 and Denali trims for 2026.

The factory wheel lineup grew alongside these redesigns. The 1st generation offered 17x7, 17x7.5, 18x7, and 19x7 wheels depending on trim and year. The 2nd generation carried a similar 17x7 to 19x7.5 spread, with documented offsets for the 18x7 and 19x7.5 wheels. The 3rd generation extends the range further, adding a 20-inch wheel as a Denali-exclusive option alongside the 17x7.5 and 19x7.5 wheels used on other trims.

Vehicle Generations & Wheel Changes

The Terrain has been through three generations since its 2010 launch, and the bolt pattern, center bore, and lug thread all changed at the 2018 redesign.

The single biggest thing to know: every Terrain from 2010 through 2017 uses a 5x120 bolt pattern with a 66.9mm center bore and M14 x 1.5 lug thread, while every Terrain from 2018 forward, including the redesigned 3rd generation, uses a 5x115 bolt pattern with a 70.3mm center bore and M12 x 1.5 lug thread. Shared hub specifications within the 2018-forward group do not establish direct-fit interchangeability on their own, since wheel width and offset still vary by generation and trim.

OEM Wheel Sizes & Fitment by Year

Exact wheel sizes and offsets varied by trim and model year, so treat these as the confirmed factory setups for each generation.

GMC Terrain, GM Theta and Theta Facelift (2010 to 2017)

Why Choose Genuine OEM Wheels?

Genuine OEM wheels are designed around the Terrain's factory specifications, including fitment, load rating, brake clearance, and original styling. For most owners, the case for OEM comes up after a curbed rim or a pothole, when the goal is simply getting back to the exact fitment the Terrain already had.

• Factory fit and specifications. Genuine OEM wheels are designed around the Terrain's factory bolt pattern, offset, and hub bore.
• Correct load rating and TPMS compatibility. OEM wheels are designed to meet the Terrain's factory load rating and to accommodate its original tire pressure monitoring system.
• Original styling and factory appearance. A stock-style wheel keeps the Terrain looking factory-correct, which matters if you plan to sell later.

OEM vs. Replica & Aftermarket Wheels

Some drivers choose replica wheels for their similar appearance or price. If your goal is to replace a damaged factory wheel, a genuine OEM wheel offers the best path to the correct fit, finish, and overall appearance, without the extra research replica shopping usually requires. We offer genuine OEM at replica price levels, often less. Here's how the two options typically compare:

How the Terrain Compares

Shoppers cross-shopping the Terrain typically also look at the Honda CR-V and Toyota RAV4, both established compact crossovers in the same general segment. The Terrain's bolt pattern, center bore, and offset are specific to GMC and General Motors' D2XX-based platform, and are not interchangeable with wheels from either competitor.

Frequently Asked Questions

What size wheels does the GMC Terrain have?
It depends on generation and trim. The 1st generation ran 17x7, 17x7.5, 18x7, and 19x7 wheels depending on year and trim. The 2nd generation used 17x7, 18x7, and 19x7.5 wheels, with ET43 confirmed on the 18x7 wheel and ET46 confirmed on the 19x7.5 wheel for 2018 to 2022 production. The 3rd generation uses a 17x7.5 wheel on Elevation and AT4, a 19x7.5 wheel on Denali, and an optional 20-inch wheel on Denali.

What is the bolt pattern on the GMC Terrain?
The 1st-generation Terrain (2010-2017) uses a 5x120 bolt pattern. Every Terrain from the 2018 redesign forward, including the 3rd generation introduced for 2025, uses a 5x115 bolt pattern.

What is the center bore of the GMC Terrain?
The 1st-generation Terrain uses a 66.9mm center bore. The 2nd and 3rd generations use a 70.3mm center bore.

What offset do GMC Terrain wheels use?
Offset is confirmed at ET43 on the 2nd-generation 18x7 wheel and ET46 on the 2nd-generation 19x7.5 wheel, both tied to 2018 to 2022 production. Offset was not consistently verified for the 1st-generation Terrain or for the redesigned 3rd generation, so those figures are not included here.

Do GMC Terrain wheels interchange between generations?
The 1st-generation Terrain uses a different bolt pattern, center bore, and lug thread than the 2nd and 3rd generations, so those wheels are not compatible with each other. The 2nd and 3rd generations share a 5x115 bolt pattern and 70.3mm center bore, but wheel width, offset, and trim-specific styling still vary enough that a wheel from one generation should not be assumed to be a direct match for the other.

What is the largest factory wheel size on the GMC Terrain?
The largest confirmed factory wheel is the 20-inch wheel offered as a separate option on the 3rd-generation Denali trim. The exact width of that wheel was not verified in the available source.

Are OEM GMC Terrain wheels better than replicas?
A genuine OEM wheel is designed around the factory fitment, TPMS requirements, and load rating, while keeping the Terrain's original appearance.

Final Thoughts

The GMC Terrain's wheel fitment splits cleanly at the 2018 redesign: the 1st generation uses a 5x120 bolt pattern with a 66.9mm center bore, while every Terrain since, including the redesigned 3rd generation introduced for 2025, uses a 5x115 bolt pattern with a 70.3mm center bore. The real variables within the 2018-forward group are wheel width, offset, and trim-specific styling, since confirmed offset values exist for the 2nd-generation 18x7 and 19x7.5 wheels but not for every configuration across the lineup. Genuine OEM wheels remain the simplest way to get factory-correct fit and styling, whether replacing a curbed rim or shopping for a full set.
