How much tire clearance do these add?

RBS-profile flares extend outward to accommodate wider tire and wheel setups while maintaining a factory-correct appearance. Measure your current wheel width and offset against your target tire diameter, then verify clearance to the inner fender before installation.

Do I need to drill new holes to mount these?

No drilling required. These flares are designed to use existing factory mounting points on the front fender. Verify bolt hole alignment on your vehicle before final tightening.

What wheel sizes and offsets work with these flares?

The RBS profile accommodates a range of wheel widths and offsets. Your specific fitment depends on tire diameter, sidewall height, and suspension setup. Consult your wheel and tire specifications, and test-fit if possible to confirm clearance to the flare inner edge.
