2024 GMC Sierra HD Dually Gets 18-Inch Wheels For The First Time11
The GMC Sierra HD range, which consists of the Sierra 2500 HD and Sierra 3500 HD, is receiving a mid-cycle refresh for the 2024 model year. Announced in early October, the update incorporates revisions to the exterior, an overhauled cockpit, along with noteworthy updates to the powertrain and capabilities. Now, GM Authority has learned that 2024 GMC Sierra HD models in the dual-rear-wheel (DRW/dually) configuration will receive a new tire and wheel combination.
While non-Denali 2024 GMC Sierra 3500 HD models with Dual Rear Wheels (DRW) are equipped with 17-inch wheels as standard, the Denali and the new-for-2024 Denali Ultimate trim levels are granted new 18-inch polished wheels, wrapped in LT235/80R18E tires. This represents the first time that the GMC Sierra HD dually has been offered with 18-inch wheels, as pre-refresh models made use of 17-inch rollers.
There is an important distinction to be made when considering a DRW model. Only the 3500 HD can be had as a dually, while 2500 HD models are available with Single Rear Wheels (SRW) only.
So, how does this line up against the competition? The Ram HD dually is limited to 17-inch wheels across all trim levels, as is the Ford F-350 dually. However, the Ford F-450 gets 19.5-inch wheels, but this model is an entirely different class of truck.
As a reminder, the 2024 GMC Sierra HD will continue to feature the naturally aspirated 6.6L V8 L8T gasoline engine, which remains rated at 401 horsepower and 464 pound-feet of torque. The 6.6L V8 L5P turbodiesel Duramax is still optional across most trims, yet is standard-affair on Sierra Denali Ultimate trim. For the refresh, the large-displacement V8 diesel has been uprated to produce 470 horsepower and 975 pound-feet of torque compared to 445 horsepower and 910 pound-feet of torque prior to the refresh.
An Allison-branded ten-speed automatic will be the sole transmission option. While this does not represent a change for the Duramax, it is an upgrade for the gasoline engine, which previously made use of GM’s six-speed gearbox.
The 2024 GMC Sierra HD will continue being assembled at the GM Flint Assembly plant in Flint, Michigan, with production set to commence in Q1 2023. Official pricing details are expected closer to the start of production.

Some big Alcoa’s would be nice!
I still like the column shift it makes the console look cleaner.
Waste of money on a 3500 dually. Going to be difficult getting narrow tread 18″ replacement tires on this low volume. Also tire rotation on these aluminum wheels require dismount since there are three unique wheels, which is same as the 17″ aluminum drw and the reason I have avoided them.
Honestly, I don’t see the reason for having larger rims. My previous dually had 16 and my 2021 has 17-inch wheels. Who cares? Going down the road few people can tell anyway. Waste of money and time!
GM went to 17 inch required in 2011 for brake clearance and load rating on 3500 drw. 18 inch doesn’t get any advantage there.
Thanks Homer! Now I know the reason. Appreciate it.
I think a 19.5 option would be a smarter choice.
When 19.5 is put on as an OEM, tire availability is no longer an LT metric. All 19.5 inch tires have a significant speed rating reduction, like 78mph from many suppliers and by T&RA standards. Some people who bought the original F450 pickups found this out the hard way.
i went from 17″ wheels to 19.5s on my dually and never looked back. Couldn’t be happier.
19.5″ Alcoas should be an option for the duallys.
Don’t know anything about the availability of 18″ tires in the proper load range for these trucks. Could be problematic.
Finally look’n right with BIG FEET. I always thought the dually looks funny with small feet.
Still too small for wheel openings!!!
