Tires

  • ​Leave the bike pump at home, you won't be needing it. Berlin-based startup BigRep has signaled a possible end to punctures by 3D printing airless bicycle tires and taking to the streets of the German capital to show them off.​
  • Recently Goodyear has rolled into the Geneva Motor Show with new tire designs that could be described as intriguing concepts at best and crazy, outlandish ideas at worst. This year's rendition is no different, hiding living moss inside to cleanse the surrounding air as the car rolls down the road. ​
  • Fresh from a dominant series of shootout victories in Europe, Continental's Road Attack 3 sports touring tires are beginning to make their presence felt in the rest of the world. New Atlas headed along to the Australian press launch to see what all the fuss is about.
  • Most mountain bikers wouldn't want shock absorbers that were simply springy air chambers with no damping. According to the guys at CushCore, however, that's exactly what tires are. Their solution? An energy-absorbing foam insert that sits inside a tubeless tire, acting as a damper.
  • Continental's new tire concepts shown at the Frankfurt Motor Show (IAA 2017) today are named ContiSense and ContiAdapt and are demonstrated in a concept tire that monitors and reports on its health and can tailor its characteristics to prevailing road condition​s.
  • ​Deflating tires are at best an inconvenience and at worst a real danger, but a new solution from car accessory maker Nonda promises to fill in the blanks, with what it says is the first tire monitor made specifically to monitor slow leaks.​​​
  • Michelin is exploring the potential for improvements in tire technology with its Vision concept tire that is airless, 3D printed, equipped with sensors, biodegradable, and not just a tire, but a tire and wheel in one.
  • ​While there are already systems that estimate tire wear, electrical engineers have developed a sensor that actually measures it in real time. The relatively simple device can reportedly track millimeter-scale changes in tread depth with 99 percent accuracy.
  • ​For some time now, crumbs of rubber from ground-up tires have been used to produce a more resilient form of asphalt. Researchers from the University of British Columbia are taking things in a different direction, however, by using polymer fibers obtained from old tires to make concrete stronger.
  • ​For decades, various manufacturers have dabbled in flat-proof bicycle tires that have a solid or foam-filled core. The problem is, those tires tend to be heavy, plus there's no way of adjusting their firmness. Italian startup MrWolf is now offering an alternative, in the form of the Banger.
  • ​In 2011 we first heard about Bridgestone's prototype AirFree Concept automobile tires, which utilized flexing thermoplastic resin "spokes" instead of compressed air. As it turns out, a just-announced bicycle version of those tires may end up beating the original to the market.
  • ​An automobile tire is composed of about 30 percent carbon black, which adds durability to the rubber. Carbon black is petroleum-based, however, meaning that it isn't entirely eco-friendly. That's why scientists have been experimenting with an alternative – namely egg shells and tomato skins.
