Colored rubber has found its way from bathroom dispensers to motorcycle tires thanks to a joint venture between Tomahawk Sport Tires and Desser, the world's largest airline-tire retreading company. That's right, they're retreads. But wait...try not to think of the semitruck retreads that dangerously litter our freeways and consider instead that 98 percent of all commercial airlines use retreads. And while there are more than 3000 truck-tire retreaders worldwide, there exist but 10 or so high-speed aircraft-tire retreaders--Desser being the largest. Their retreaded tires are FAA certified up to 225 mph, and all are scrutinized with high-dollar Laser Shearography technology to ensure structural integrity of the carcass. Finally, they're DOT approved for high-speed applications. These colored retread rubbers come in a variety of compounds and are available in black, blue, green, red and yellow.
