Best of both rimming worlds – Flat-Out Bang tire insert on the front for the fast-rolling impacts and sturdy Flat- Out Core tire insert on the back for hits. Best combo for the starters and shreders, who believe in weight saving while focusing on going fast, not wasting time on changing rims. It’s a nice gift for a buddy who wastes time at the parking lot chasing tires after each braap. Go, support a homie!
