The Trekker Bicycle Tire Rug is made entirely of recycled bicycle inner tubes! Even better- it is entirely indoor or outdoor! The Trekker offers a wonderful texture and grey tones, and when you look really close you will still see some of the psi ratings and other inner tube info. For any cycling enthusiast- or recycling for that matter- this is a great way to bring modern styling to your home, inside or out. Available in two sizes.
