Tires

The studs in their extended state

Studded tires may make it easier to drive on ice, but those same studs will quickly wear down when used on dry asphalt – plus, they'll create a very rough, noisy ride. The problem is, most winter drivers encounter both types of road conditions, often even on the same trip. That's why Nokian has created a snow tire with retractable studs.  Read More

A prototype of the system, with its wacky two valve stems

So, you've upgraded your mountain bike's clincher tires to tubeless, and now you figure you're all up-to-date and on the cutting edge, right? Well, perhaps not for much longer. German tire-maker Schwalbe and bike parts manufacturer Syntace have developed a tubeless dual-chamber tire and wheel system, that they claim should offer better performance than your current old-school single-chamber tires.  Read More

The Airgun might look like a drill, but it's a battery-powered compressor

Need to pump up a ball, bike tire or whatnot, but don't feel like doing a lot of manual pumping? You could take the item up to your local gas station and use its compressor, but Airman is hoping that you'll use its Airgun instead.  Read More

The WV80 HO is uses Non-Pneumatic Tires

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

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.  Read More

In racing conditions that rely on tenths of seconds per lap to be the difference between w...

Tire technology plays a critical role in motor racing. It seems an obvious point to make, but events at this weekend's opening round of the 2013 Supersport season hammer home just how important – and how challenging – it is to get the rubber right.  Read More

The SymTyre-S300 is a machine that cuts up discarded tires, so they can be flat-packed for...

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.  Read More

The BTPS Bike Tire Pressure System in use

It’s becoming more and more common for new cars to have air pressure sensors built into the wheels, so that drivers can receive real-time air pressure readings for each tire. So, why don’t bicycles have them? Well, perhaps they should ... and that’s the idea behind the BTPS Bike Tire Pressure System.  Read More

The mountain bike version of the Energy Return Wheel, being put to the test

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
