How much tire clearance do these flares add?

RBS flares are designed for stock wheel and tire sizing. If you're running wider tires or aggressive offsets, measure your current sidewall-to-panel gap before ordering and verify fitment against your specific setup.

Do these require drilling into the body?

No—these mount using factory attachment points. You'll work with existing holes and fasteners on the vehicle, eliminating the need for new drilling or custom fabrication.

What compatible wheel sizes work with these flares?

These are engineered around stock wheel diameters and typical offset ranges. If you're considering non-standard wheel or tire combinations, confirm clearance with your wheel and tire supplier before finalizing your build.
