How much additional tire clearance do these fender flares provide?

The flares extend the body line outward to accommodate wider tires and wheels within the wheel well. Measure your current setup against your desired tire and wheel size to confirm fitment before ordering.

Do I need to drill into my bumper or body to install these?

No drilling is required. These flares are designed to attach at factory mounting points. Confirm fastener hole alignment with your specific vehicle configuration before installation.

What wheel sizes and offsets will these accommodate?

Wheel fitment depends on your vehicle's suspension setup and desired stance. Compare your wheel diameter and offset against the extended body line these flares create, and verify tire clearance at full lock and ride height.
