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.
