How much tire clearance do these flares add?

RBS-style flares provide modest extension over the stock fender line. Measure your current tire sidewall-to-fender gap before ordering; these flares work best when you're adding a tire one size up from factory spec. If you're running significantly larger rubber, verify fitment against your wheel and suspension setup.

Do I need to drill holes to install these?

These flares are designed to integrate with factory mounting points on your vehicle. Check your OEM fender for existing holes or attachment bosses before installation. Some mounting may require fastening hardware not included in this kit — verify your vehicle's structure beforehand.

What wheel sizes and offsets work with these flares?

RBS flares accommodate a range of wheel sizes and offsets, but fitment depends on your suspension geometry and tire choice. Before purchasing, confirm your wheel diameter and offset against your current fender clearance. A lower offset wheel will sit further out and may require the extra room these flares provide; measure your current setup to be certain.
