Overview

The Slicy Smooth is an anti-pinch flat tire insert made from high-density closed-cell EVA foam. The 2.0 version features a honeycomb skin for better shock absorption and increased foam density, plus a slicker finish so sealant does not stick to the foam. The cut-out center shape optimizes air and sealant flow. Sold per unit — cut to fit 29", 27.5" or 26" wheels.
