The upcoming Chevy Silverado ZR2 Trail Boss is equipped with larger tires than the current Chevy Silverado Trail Boss, running 33-inch rubber compared to the current model’s 32-inch tires.
Although General Motors has yet to provide any sort of official confirmation, the upcoming Chevy Silverado ZR2 Trail Boss is expected to offer even greater off-road capability than the current Silverado Trail Boss model. That includes larger Goodyear Wrangler Territory tires, sized at 275/70R18, as compared to the 275/65R18 tires on the current Trail Boss.
The upcoming Silverado ZR2’s tire spec was confirmed via photos of a prototype model caught testing on some real-world roads. The ZR2 prototype is also running five-spoke wheels with a black finish.
What’s more, the Silverado ZR2 appears to have equivalent wheel well clearance despite the taller tires, which suggests that the new off-roader could come with even an taller suspension lift than the current Trail Boss model, the latter of which offers a two-inch lift from the factory.
While 33-inch tires are considerable, they don’t quite match up to the 2021 Ford F-150 Raptor’s 35-inch and 37-inch tire options. Nevertheless, the new Chevy Silverado ZR2 should offer a tangible increase to off-road capability over the current Trail Boss model. Standout features include a new front end that deletes the front air dam, with loads of ground clearance as well as a heavy-duty skid plate to protect the greasy bits underneath. In back, the new Silverado ZR2 is expected to introduce several revisions, which will combo with the new front end to offer some generous approach and departure angles.
The manner in which the upcoming Silverado ZR2 will join the model lineup is a bit unclear at the moment, but one possibility is that it will join the “standard” Silverado Trail Boss as a new, more capable iteration, with two Silverado Trail Boss models offered in parallel. Alternatively, the new Silverado ZR2 could replace the current Silverado Trail Boss model outright.

LT type rather than a P metric as well. LT275/70R18 is common size with current 2500 and 3500SRW. Can’t make out the load range though. Typically 1500 LTs are C load and 2500/3500 are E load.
Although they are larger on the 18″, its the same diameter as the 20″ tire they used 2019-2020 on the 20 inch wheel option. Those were 275/60R20 which is a 33″ tire.
GM switched tires on the 20 inch option on the Trail Boss for 2021 to an LT265/6R20 Goodyear Wrangler Territory MT which is just over a 32 inch tire.
You forgot to mention the ZR2 Silverado will have super beefed up Multimatic DSSV shocks as well.
Will it be offered with a 6.2
I’m convinced this will be a upgrade package on the standard trail boss. No way will it be a rival for the Raptor and TRX. More so a direct rival to the upcoming F150 Tremor trim which basically offers the same as this.
I agree Jason. And I’m cool with that. This seems like a great truck without the crazy price of a Raptor or TRX.
I was expecting a power plant upgrade
GM needs to replace the Goodyear tires with products that perform better – BFG, Toyo or Kenda make better tires in the sizes offered
I have had the tires you suggest.. the Duratrac’s are better. They last longer and are quieter. I was a BFG guy for a long time and their KO 2’s are a loud tire after 20K miles.
