For the upcoming model year, General Motors recently introduced the most-capable off-roading Colorado yet, the 2024 Chevy Colorado ZR2 Bison. Replacing the current 2023 Colorado ZR2 Desert Boss as the range-topping variant, the Bison receives a bevy of upgrades and enhancements over the “regular” ZR2, one of which being the massive wheel and tire package. Now, here’s why the 2024 Colorado ZR2 Bison gets a bed-mounted spare as standard fare.
The all-terrain Bison model will be equipped as standard with a bed-mounted spare tire, and the reasoning behind this unconventional decision is quite simple: the 35-inch wheel and tire combo doesn’t fit underneath the truck bed. Notably, this is where the spare tire is normally located for all other Colorado trims.
This is an interesting solution that General Motors came up with to ensure every Colorado model is equipped with a spare tire. In fact, The General actually lengthened the wheelbase of the third-gen midsizer to accommodate the 17-inch beadlock-capable wheels and 35-inch OD Mud/Terrain tires that the Bison is equipped with.
As a reminder, the 2024 Chevy Colorado ZR2 Bison ups the ante in regard to all-terrain prowess, and includes a suite of off-roading features. These includes Boron steel skid plates and rocker protectors, segment-exclusive Multimatic front and rear Jounce Control Dampers and DSSV dampers. Off-road specs include 12.2 inches of ground clearance, as well as a 38.2-degree approach angle, 26-degree departure angle, and 26.9-degree break-over angle.
In regard to powertrain, the Bison features the turbocharged 2.7L I4 L3B gasoline engine, which is in the Turbo High-Output tune and rated at 310 horsepower and 430 pound-feet of torque. Output is directed to the ground (or mud) through the second-gen GM eight-speed automatic transmission, as well as a two-speed transfer case and power-locking front and rear differentials.
