How much tire and wheel clearance do these flares allow?

Khan-style flares provide modest extension for wheels up to stock sizing plus modest aftermarket diameter. Verify your specific wheel and tire combo against the flare profile before purchase — fitment depends on your offset and suspension geometry.

Do these flares require drilling into the fender or door panels?

No. These bolt directly to factory mounting points on the existing fender. No drilling or cutting is necessary for installation.

What prep and finish work is required before painting?

Sand and prep the surface with your preferred grit before applying your chosen base coat and clear. Standard automotive prep procedures apply — refer to your paint supplier's technical data for your specific system.
