Our parking stops are made using a 100% recycled mix of natural rubber and styrene-butadiene rubber, which is compression molded to make a durable and more viable alternative to traditional concrete and plastic stops. These are designed to withstand extreme temperature variations, UV light, moisture, oil, road salt, and damage, and do not corrode, crack, crumple, or chip. Our chevrons are molded into the rubber and this makes our TireBoss a more durable alternative to competitors, which merely use reflective surface-applied tape.
