GMC Terrain Hubcap and Wheel Cover: Matching Trim Level to Part Number

When it comes to maintaining the clean, factory-fresh look of your GMC Terrain, few details matter as much as a properly fitted hubcap or wheel cover. Whether you have lost one to a curb scrape or simply want to refresh the appearance of your wheels, ordering the correct replacement requires more than just knowing your vehicle’s year. The trim level your Terrain wears plays a defining role in determining the wheel size, cover style, and OEM part number that will fit precisely. Understanding how these variables connect is the first and most important step before you shop GMC Terrain wheel covers.

Why Trim Level Determines Wheel Size on the GMC Terrain

The GMC Terrain has been offered across multiple generations, and each generation carries a range of trim levels   from the entry-level SL and SLE to the more feature-rich SLT, the rugged AT4, and the premium Denali. Each of those trims comes with a factory-specified wheel diameter, and that diameter directly affects which GMC Terrain hubcap and wheel cover will fit your vehicle.

On second-generation Terrain models (2018 and newer), the SLE base trim is equipped with 17-inch silver-painted aluminum wheels. When you step up to the SLT, those wheels grow to 18-inch machined aluminum units with dark gray painted accents. The Denali sits at the top of the lineup with 19-inch ultra-bright machined aluminum wheels. The AT4, designed with an off-road personality, returns to 17-inch gloss-black aluminum wheels paired with sport terrain tires.

For first-generation Terrain models running from 2010 through 2017, wheel sizing worked somewhat differently. Many 2010–2013 models came standard with 17-inch alloy wheels, while certain upper trims in the 2014–2017 range also ran 17-inch alloys before the second generation brought broader size differentiation across the lineup.

The key takeaway is straightforward: a GMC Terrain 17 inch wheel cover will not properly seat on an 18-inch or 19-inch rim, and vice versa. Ordering based only on the model year without confirming the trim level can result in a cover that either fails to lock in securely or looks visually out of place on the wheel face.

How Terrain Wheel Cover by Trim Breaks Down Across the Lineup

Understanding Terrain wheel cover by trim is the most reliable method for narrowing your search before you ever look at a part number.

SLE Trim   17-Inch Wheel Covers

The SLE serves as the baseline for the second-generation Terrain and comes fitted with 17-inch silver-painted aluminum wheels. Wheel covers and Wheel Skins designed for this fitment are among the most widely available on the market. OEM center caps for SLE-spec wheels typically carry silver or charcoal painted finishes, and aftermarket options are offered in both chrome and black finishes to match personal style preferences.

Wheel Skins designed specifically for the 17-inch SLE wheel are engineered to snap securely over the existing alloy surface without requiring any modification. They give the wheel a refreshed, showroom-quality appearance while protecting the original finish from road debris, seasonal salt exposure, and general wear.

SLT Trim   18-Inch Wheel Covers

Moving up to the SLT, the Terrain wears 18-inch machined aluminum wheels with dark gray painted accents. This is an important distinction because the wheel cover or Wheel Skin meant for this fitment must match both the diameter and the spoke pattern of the SLT-specific wheel design. An 18-inch GMC Terrain wheel cover has a different retention ring diameter and a different spoke layout than the 17-inch version, so cross-compatibility between the two is not possible.

OEM center caps for the SLT’s 18-inch wheels are available in machined and dark gray accent finishes, and aftermarket Wheel Skins are offered in chrome and gloss black to complement or contrast the original look.

AT4 Trim   17-Inch Gloss-Black Wheels

The AT4 trim returns to a 17-inch wheel but with a distinctly different design   gloss-black painted aluminum with an aggressive spoke pattern suited to its trail-ready character. Even though the AT4 shares a 17-inch diameter with the SLE, the wheel profile and spoke design differ significantly. A wheel cover or center cap sourced for the SLE will not have the correct fitment profile for the AT4’s wheel design. When replacing or upgrading covers on an AT4, it is essential to source covers that match the AT4-specific bolt pattern and face geometry.

Denali Trim   19-Inch Bright-Finished Wheels

The Terrain Denali sits at the top of the lineup and wears 19-inch ultra-bright machined aluminum wheels with gray painted accents. This wheel size is unique to the Denali within the Terrain family, and center caps or decorative covers for this fitment are correspondingly specific. If you own a Terrain Denali and need a replacement center cap, you will need to source a part that is explicitly listed for the Denali’s 19-inch wheel specification and its associated part number.

GMC Terrain Fitment: Confirming the Right Part Number

Part number verification is where many buyers run into difficulty. For GMC Terrain fitment, the part number on a center cap or wheel cover is tied not just to the year of the vehicle but also to the specific wheel that was installed at the factory. This matters because even within the same model year, two Terrain owners can be driving vehicles with entirely different wheel designs depending on which trim they purchased.

Here is a general overview of OEM part numbers that have been associated with different Terrain wheel configurations:

• OEM Part #9597570   Fits select 2010–2014 Terrain 17-inch wheels (silver painted finish, 6 5/8-inch diameter cap)
• OEM Part #9597571   Fits select 2010–2016 Terrain 17-inch wheels (chrome finish, 6 5/8-inch diameter cap)
• OEM Part #9597973   Fits 2010–2016 Terrain 17-inch alloy wheels (silver painted finish, 6 1/2-inch diameter cap)
• OEM Part #22884890   Fits 2013–2016 Terrain 17-inch wheels (satin finish center cap)
• OEM Part #23446994   Fits 2016–2017 Terrain 17-inch alloy wheels (silver finish, 6 5/8-inch diameter cap)
• OEM Part #23446997   Fits 2016–2017 Terrain wheels (charcoal painted finish)
• OEM Part #84072880   Fits 2016–2017 Terrain 17-inch wheels (black painted finish)

For 2018 and newer Terrain models, center cap part numbers vary based on the trim-specific wheel design. The most reliable method to confirm the correct part number for your vehicle is to locate the wheel number stamped or etched onto the back of your existing wheel or original center cap. That wheel number, often a four- or five-digit code, acts as a direct reference point for finding the matching cover or cap.

What to Check Before You Order a GMC Terrain 17 Inch Wheel Cover

Even for the most common Terrain fitment   the 17-inch wheel on SLE and AT4 trims   there are several details worth confirming before placing an order.

• Wheel diameter   Measure the diameter of your existing wheel from inside the rim to confirm it is truly 17 inches, as trim variations can sometimes include upgraded wheel packages that change the stock size.
• Spoke pattern and face design   Wheel covers and Wheel Skins are designed to mirror a specific spoke layout. An SLE 17-inch wheel and an AT4 17-inch wheel look quite different from the front face, and a cover designed for one will look noticeably wrong on the other.
• Center bore and cap diameter   OEM center caps have precise diameter specifications, typically between 2 5/8 inches and 6 5/8 inches depending on the wheel design. The cap must seat flush and lock securely into the center bore of the wheel.
• Finish compatibility   Whether you prefer the original silver painted look, a polished chrome finish, or a black or charcoal aesthetic, make sure the cover finish is consistent with your wheel’s color and your vehicle’s exterior trim.
• Retention system   Quality aftermarket Wheel Skins use a retention ring or clip system to hold securely to the wheel at highway speeds. Covers without a reliable retention mechanism can loosen or detach over time, which is both a safety concern and a cosmetic issue.

OEM vs. Aftermarket Wheel Covers: Materials and Quality

Whether you are replacing a missing center cap or upgrading the entire wheel face with a set of Wheel Skins, the material and construction quality of the cover you choose will determine how long it lasts and how well it holds its appearance.

OEM center caps are manufactured from automotive-grade ABS plastic and are finished with two or more layers of clear coat to protect against UV exposure, moisture, and road chemicals. Factory caps are designed to integrate seamlessly with the wheel’s design and carry the GMC badge or emblem at the center. When sourced in excellent condition, OEM caps offer an exact-match replacement that maintains the vehicle’s original appearance.

Aftermarket Wheel Skins are similarly constructed from high-impact ABS plastic and offer a practical way to refresh or upgrade the look of factory alloy wheels without replacing the wheels themselves. A quality set of Wheel Skins snaps over the existing wheel surface using a patented retention system, covering the entire face of the alloy to create a chrome, black, or polished appearance. They are model-year and trim specific, meaning they are engineered to correspond exactly with the spoke count, spacing, and outer diameter of the wheel they are designed to cover.

The most durable covers available   whether OEM or high-quality aftermarket   use UV-stabilized materials and multi-layer finishes that resist fading, cracking, and peeling across seasons. This matters particularly in climates with harsh winters, road salt exposure, or intense summer sun.

How to Shop GMC Terrain Wheel Covers Confidently

When you are ready to shop GMC Terrain wheel covers, the process goes much more smoothly when you walk in   or browse online   with the right information already in hand.

Start by confirming your Terrain’s model year, trim level, and the wheel diameter currently on the vehicle. If the original center cap is still present, note any part numbers or identification codes printed on the rear of the cap. If the cap is missing, look for a number stamped on the back of the wheel itself.

From there, filter your search by wheel diameter first (17-inch, 18-inch, or 19-inch), then by finish style, then by the specific part number or product ID that corresponds to your wheel design. Reputable suppliers like HubCaps.TV carry a range of OEM and aftermarket options organized by year, make, model, and trim, which makes it significantly easier to confirm GMC Terrain fitment before you commit to a purchase.

If you are ever uncertain whether a specific cover will seat properly on your wheel, do not hesitate to contact the supplier directly with your wheel number or trim details. A precise fit matters far more than a lower price on the wrong part.

Final Thoughts on Terrain Wheel Cover Matching

The GMC Terrain is a well-designed compact SUV, and its wheel aesthetics are a meaningful part of the overall exterior presentation. Whether your Terrain rides on 17-inch SLE alloys, 18-inch SLT machined wheels, or the Denali’s 19-inch bright-finished rims, matching the correct GMC Terrain hubcap and wheel cover to your specific trim and wheel design ensures a clean, factory-accurate result.

Taking the time to confirm your trim level, wheel diameter, spoke pattern, and part number before ordering prevents the frustration of a mismatched fit. And when you choose a cover made from high-quality automotive-grade materials with a proper retention system, you are investing in a replacement that will stay in place, resist the elements, and keep your Terrain looking its best for the long term.
