The Tannus Solid Tires Never Go Flat

tannus_solid_bicycle_tires_1

Getting a flat tire while riding your bike is a massive pain in the ass. But if you outfit them with a set of Tannus tires, this concern may become a thing of the past. These tires require no inflation since they’re a solid block made of a special foamy resin called “Aither”.

Made from a very special Micro Closed Cell Polymer Resin “Aither”, Tannus tire uses a foaming technology. And, it may look similar to that used in many lightweight sports shoes, but it is totally different from any other foaming technology both in terms of its process or the condition. It is made from the one-and-only material “Aithercompound” with a very unique foaming process.

They’ll allegedly withstand puncture, and never go flat, while suffering from very little rolling resistance. The tires come in 12 different colors, and 3 different hardness types (soft, regular, and hard). They’ll set you back between $50 and $70, and there are different types and sizes to accommodate bikes of all sorts.

Goodyear Is Developing An Electricity-Generating Tire

goodyear-bho3.0.0

Think for a minute about how much energy is wasted in a car. All that gas it burns to get it rolling is almost entirely dissipated and lost as heat in the brakes as it slows back down, while the rest goes to combatting air resistance and drivetrain inefficiencies. By some accounts “only about 14%–30% of the energy from the fuel you put in a conventional vehicle is used to move it down the road.” Newer electric vehicles have started harvesting some of that energy back through regenerative braking, but Goodyear is taking things a couple of steps further by developing a special tire that itself generates power. The concept is called BHO3, and it takes both the friction heat as well as the deformations the tire undergoes while driving to generate an electric current, which is then presumably fed back into the car’s batteries.

To do this, the BHO3 is lined with a fishnet pattern of thermo/piezoelectric material. This net turns the heat into electrical current, and its piezoelectric properties also allow it to harvest energy from the tire as it deforms during driving. To keep the tire from overheating, there’s also a cooling system in the sidewalls.

It’s only a concept at the moment so don’t expect to see it on the road any time soon. But it’s nice to know people are constantly working to wean us off fossil fuels.

RightPSI Tire Cap Lets You Check Pressure At A Glance

rightpsi

If your car is not equipped with a fancy Tire Pressure Monitoring System (TPMS), then you have to do manual checks now and then. Having the right air pressure in your tires is essential for safety and mileage, but checking manually is a pain in the posterior, especially if it’s really cold outside. The RightPSI tire caps change colour depending on whether you’re right on target, or have fallen off. A simple glance at your wheel can tell you if it needs attention. Heck, even if you have TPMS, RightPSI can be useful since it’ll tell you which of your tires is going flat, without you having to test them one by one. The way it works is you purchase a PSI specific set, which you cannot change if ever you change cars or tires. At $25 for a set of 4 though, you won’t be breaking the bank.

Winter Tires With Retractable Studs Possibly On The Horizon

nokian-retracting-studs

With the snowy Apocalypse having fallen hard on much of the south over the last few weeks, there’s no doubt some people’s minds have been on the topic of winter tires. They are, after all, made to perform drastically better in icy and snowy conditions, though there is one step above that: winter tires with studs. That’s the ultimate in grip in ice, but it’s also a noisy, abrasive pain between snowfalls so few people opt for them. Now, Nokian Tyres has announced the development of a winter tire with retractable studs. You notice it’s really slippery? Press a button on your dashboard and the studs extend, only to retract again once you’ve made it out of the ice and snow. It’s really the best of both worlds, and it’s not available for purchase. Unfortunately. There aren’t even concrete plans to bring these to market, but the fact that the technology now exists mean that’s missing is enough demand. A few more of the store we’ve seen lately and the market just might change…
