The Chevy Colorado ZR2 is a popular choice among off-road enthusiasts due to its robust capabilities and adaptable design. One common modification for any off-road vehicle is upgrading the tires for better traction and performance. However, it’s crucial to select the right tire size to avoid any rubbing or clearance issues. This article answers key questions about the optimal tire sizes for the Chevy Colorado ZR2, ensuring a smooth upgrade.

What Size Tires Can the Chevy Colorado ZR2 Fit Without Rubbing?

The Chevy Colorado ZR2 comes factory-equipped with 31-inch tires (265/65/R17). These tires offer a balanced performance, providing adequate clearance and minimal risk of rubbing under normal driving conditions and moderate off-roading. For those looking to enhance their ZR2’s capabilities without modifying the suspension, the maximum tire size recommended without any modifications is typically around 32 inches (265/70/R17).

When considering upgrading to 32-inch tires, it’s essential to ensure that the tire’s width and profile will not interfere with the vehicle’s suspension and wheel wells, especially during full articulation or when the steering is fully turned. These tires offer a slight increase in ground clearance and can handle rougher terrain than the standard factory-issued tires.

What Are the Biggest Tires I Can Put on My Chevy Colorado ZR2?

For Chevy Colorado ZR2 owners looking to maximize their tire size, the largest size recommended without significant modifications is 33 inches (275/70/R17). Fitting 33-inch tires on a ZR2 may require minor modifications such as adjusting the wheel well liners or slight trimming of the fender flares to avoid rubbing at full turn or during suspension compression.

However, if you’re willing to undertake more extensive modifications, such as a lift kit or more aggressive adjustments to the fenders and wheel wells, you could potentially fit tires up to 35 inches. It’s important to note that increasing tire size beyond 33 inches could affect the vehicle’s handling, fuel efficiency, and might require additional changes to the gearing and suspension to maintain drivability and comfort.

Choosing the right tire size for your Chevy Colorado ZR2 is crucial for maintaining its performance and drivability. The ZR2 can comfortably accommodate up to 32-inch tires without any modifications, and up to 33-inch tires with minor adjustments. If you aim to go bigger, be prepared for more significant modifications and consider how these changes will affect your vehicle’s overall functionality. Always consult with a Bruner professional to ensure that your upgrades enhance your driving experience without compromising the vehicle’s integrity.
