Polaris' military-grade WV850 HO ATV rolls on non-pneumatic tires

By - November 19, 2013 12 Pictures
There’s nothing that ruins going to work like having your tires shot out with a .50 caliber machine gun round. If that happens to you a lot, and your commute is across open fields and through the woods, you might want to consider the Polaris Sportsman WV850 HO with Terrain Armor. This military-grade All-Terrain Vehicle (ATV) abandons traditional inflatable tires for Non-Pneumatic Tires (NPT) that feature a flexible polymer honeycomb. Read More

Roadless wheel concept adjusts to all terrains

By - November 6, 2013 14 Pictures
Graduate student Ackeem Ngwenya has combined the 6000 year-old wheel with modern materials to develop a new type of all-terrain wheel assembly that switches from narrow to wide tread at the turn of a screw. His Roadless wheel system, while envisioned for rural applications in his native Malawi, has the potential to be as big a change to road (and off-road) transport as was the introduction of anti-lock braking.

SymTyre machine makes old tires flat-packable

By - January 16, 2013 2 Pictures
Tires are one of those things that our society goes through a lot of, yet their disposal can be problematic. Being round and containing a large air cavity, they’re not exactly the most efficient things to store or transport. Those that don’t get recycled can end up collecting water and acting as breeding grounds for mosquitoes, or becoming part of giant “tire mountains.” A new device, however, is designed to cut them apart so they can be flat-packed – thus reducing the space they take up, and maximizing the amount that can be transported at once.

Prototype wheels could take the flats out of mountain biking – and driving

By - October 30, 2012 5 Pictures
Puncture-proof tires that incorporate a flexible internal matrix instead of air are nothing new, in and of themselves. In the past several years, we’ve seen prototypes from the likes of Michelin, Amerityre, Goodyear and Bridgestone. Colorado-based Britek Tire and Rubber has also been developing something similar, known as the Energy Return Wheel. While the ERW is intended mainly for cars, the company recently released a video showing a prototype set of the wheels in use – on a mountain bike. Read More

Goodyear’s self-inflating tire tech for commercial vehicles leaves the lab

By - September 20, 2012 3 Pictures
In the days before full-service gas stations went the way of the dodo, in addition to filling ‘er up, the attendant would sometimes check the tire pressure. These days that task, along with actually pumping the fuel, has totally fallen back on the driver, but it’s a job that is easily overlooked. This leaves many people driving around on tires at less than optimal pressure resulting in reduced performance and fuel economy. For the past year, Goodyear has been developing its self-inflating tire technology that's designed to keep tires inflated at the optimum pressure and the company is now set to debut the technology in Germany.

Bicycle wheelsets with no-flat tires premounted

As a number of riders in this year’s Tour de France can attest, getting a flat after hitting a tack or nail on the road not only causes delays, but can also be downright dangerous. Last year, Hutchison released its airless Serenity tire that is 100 percent flat-proof, but cyclist Steve Boehmke found they were fairly difficult to install and only fitted a very specific sized rim. To overcome this, he’s built wheelsets with the tires pre-mounted that are designed to take the hassle out of getting them on your bike. Read More
