Will these flares give me additional tire clearance?

These are body panels that extend over the wheel opening. They follow the factory fender line and add coverage, but tire clearance gain is minimal — they're designed for appearance and protection from road debris, not significant suspension lift clearance.

Do I need to drill holes in my truck to mount these?

No. The flares use factory mounting points with pre-drilled rivet holes that align with your existing anchor locations. No drilling required.

What size tires can I run with these flares installed?

Tire and wheel sizing is determined by your suspension setup and available clearance, not the flares themselves. The panels sit in the factory fender area and don't restrict fitment — verify your wheel and tire diameter against your vehicle's factory specs before installation.
