- 2027 Silverado ZR2 upgrades from 33-inch to 35-inch Goodyear Territory MT tires
- Redesigned front bumper features large tire cutouts and new protective skid plate
- Trail Boss variant also receives styling updates but retains current tire specifications
- Changes suggest Chevrolet’s strategy to compete directly with Ford F-150 Raptor and Ram TRX
- Next-generation Silverado 1500 launch expected for 2027 model year
Recent spy photography has captured the upcoming 2027 Chevrolet Silverado ZR2 undergoing testing with significant upgrades, most notably larger 35-inch tires that mark a departure from the current model’s 33-inch specification. The enhanced off-road pickup appears designed to challenge established competitors in the high-performance truck segment.
Enhanced Off-Road Capabilities Take Center Stage
The most significant development centers on tire sizing, with test vehicles equipped with 35-inch Goodyear Territory MT tires measuring 285/75 R-18, compared to the current generation’s 275/65R-18 specification. This upgrade represents Chevrolet’s apparent strategy to match capabilities offered by the Ford F-150 Raptor and Ram 1500 SRT TRX, though official performance comparisons remain unconfirmed.

Redesigned Front End Emphasizes Functionality
Spy photographs reveal substantial front fascia modifications, including enlarged tire clearance cutouts flanking a revised bumper design. A prominent skid plate extends below the new front structure, providing additional underbody protection for off-road driving scenarios.
Trail Boss Variant Receives Moderate Updates
Alongside the ZR2, Chevrolet’s Trail Boss trim has been photographed with updated styling elements. While maintaining alignment with the broader Silverado lineup refresh, the Trail Boss retains current tire specifications rather than adopting the ZR2’s enhanced rubber.

The current Silverado ZR2 launched as Chevrolet’s answer to Ford’s Raptor dominance in the off-road pickup segment. However, tire limitations and track width specifications have historically positioned it below competitors’ capabilities. The next-generation model appears designed to address these competitive disadvantages.
Chevrolet has not announced official timing for the 2027 Silverado reveal, though multiple prototype sightings suggest an imminent unveiling. The complete lineup details, including powertrain specifications and pricing, await official confirmation.
