GMC Hummer EV Wheels and Rims

GMC Hummer EV Aftermarket Wheel Fitment

The GMC Hummer EV is GM's full-size electric truck and one of the heaviest, most over-built vehicles in our catalog. It launched as a 2022 model on GM's BT1 EV platform, the same chassis architecture that underpins the Chevrolet Silverado EV and the Cadillac Escalade IQ. Hummer EV is sold in two body styles, a Pickup (EV1, EV2X, EV3X) and an SUV (EV1 SUV, EV2 SUV, EV3 SUV), and both run the same wheel hub spec. Every Hummer EV from 2022 and up runs 8x165.1 (also called 8x6.5) with a 124.1mm hub bore, an M14x1.5 thread, and an 8 lug count. The truck ships from the factory on 35 inch tires, weighs more than five tons, and runs an 18 inch front and rear brake. The wheel selection that fits a Hummer EV is therefore narrower than a typical half-ton truck. We measure the Hummer EV at stock height as a square fitment. Pick your build below.

Find Your GMC Hummer EV Fitment

Pick your body style to see wheels and rims that fit your specific Hummer EV. The Pickup and the SUV share the same 8x165.1 bolt pattern, the same 124.1mm hub bore, and the same stock-height fitment window. We list both as the same catalog row.

The GMC Hummer EV Bolt Pattern

Every GMC Hummer EV from 2022 and up runs 8x165.1 with a 124.1mm hub bore. The imperial nickname for this pattern is 8x6.5 because 165.1mm equals 6.5 inches. The lug count is 8, the thread pitch is M14x1.5, and the lug type is a standard tapered nut. 8x165.1 is the heavy-duty truck bolt pattern, the same nominal pattern used on the GMC Sierra 2500, the Chevrolet Silverado 2500, and the Ram 2500. The Hummer EV sits in the HD truck class for wheel selection even though it is marketed as a consumer truck, because the vehicle weight, the suspension loads, and the wheel hub were all engineered to HD-truck spec.

The Hummer EV is GM's all-electric, full-size truck and SUV built on the BT1 EV platform. That same platform underpins the Chevrolet Silverado EV and the Cadillac Escalade IQ. The chassis architecture is shared, the battery layout is shared, and the wheel hub spec is shared at 8x165.1 with the 124.1mm centerbore across the three BT1 EV vehicles. That said, the Hummer EV's body, suspension travel, and brake package are unique to the truck, so even within the BT1 family we measure Hummer EV fitment separately.

Why Hummer EV Fitment Is Its Own Category

The Hummer EV is over-built in every dimension that matters for a wheel. It ships on 35 inch tires from the factory, the largest stock tire on a current production GM vehicle. It weighs more than five tons, which puts it well above the load rating of most aftermarket half-ton-class wheels. The front and rear brake assemblies are both 18 inches tall, which limits the smallest diameter aftermarket wheel that can clear the caliper. The hub bore is 124.1mm, which is larger than the typical half-ton truck and means most 8x165.1 wheels designed for a Silverado 2500 or Ram 2500 either match or require a hub centric ring.

What this means for aftermarket wheel selection. The aftermarket wheel you put on a Hummer EV needs to be rated for the load (the wheel manufacturer's load rating must meet or exceed the vehicle's per-corner weight at the maximum tire size you plan to run). It needs to clear the 18 inch brake (which means 22 inch is typically the practical minimum diameter, with most owners running 22 inch to 24 inch). And the wheel needs the correct 124.1mm centerbore or a properly sized hub centric ring. The Hummer EV is not a platform where guessing at fitment works. We measure it directly and the catalog reflects the narrow window where a wheel actually fits this truck.

How We Confirm Fitment on GMC Hummer EV Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the Hummer EV. For this truck that means clearance from the wheel to the fender at stock height, gap between the back of the wheel and the suspension, brake caliper height on the 18 inch front and rear brake, hub protrusion past the 124.1mm centerbore, lug seat depth on the 8-lug pattern, and load rating verification given the truck's curb weight. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. We don't pull specs from manufacturer sheets the way most retailers do.

Every wheel we recommend is backed by our Fitment Guarantee. If a wheel does not fit, we pick up the wheels and refund 100 percent. No risk to you.
