Bridgestone tests Russian dandelion as raw material for tire rubber

By - June 20, 2012 2 Pictures
Taraxacum officinale, or dandelion, the herb used for tea and salads, is an excellent liver tonic and diuretic. But there’s another variety of dandelion known as Russian dandelion, aka Taraxacum kok-saghyz, which Bridgestone Americas is researching as raw material to make high-quality rubber for car tires. After preliminary tests, the company said it will continue to assess the material at its technical laboratories in Akron and Tokyo in coming months, and will follow that with larger-scale testing in 2014.

Soybean oil could make for longer-lasting, greener tires

It’s good for the environment when manufacturers can find ways of using less fossil fuels, while consumers – along with the environment – benefit when products last longer. Now, thanks to the humble soybean, both parties may be able to get what they need. Researchers from the Goodyear Tire and Rubber Company have discovered that soybean oil can help reduce the amount of petroleum used in tires, while also extending those tires’ tread life. Read More

ADAPTRAC changes mountain bikes' tire pressure on the fly

By - April 17, 2012 8 Pictures
Like a lot of other factors involved in mountain biking, setting the air pressure of the tires is a matter of compromise. Keep them too soft, and you can’t go as fast as you’d like on smooth stretches of the trail – keep them too hard, and they’ll just bounce off of roots and rocks instead of gripping them. As it stands, most bikers go for a “Jack of all trades, master of none” setting, that allows for some traction and some speed. The folks at ADAPTRAC, however, apparently think that such a compromise shouldn’t have to be made. Their new system allows riders to inflate or deflate their tires as conditions dictate, while they’re riding. Read More

Bridgestone's airless tires are designed to never go flat

By - December 2, 2011 1 Picture
This week at the Tokyo Auto Show in Japan Bridgestone showed off its latest development – puncture-less air-free tires. The tires are still in the concept phase, but have been successfully tested on single-person vehicles in Japan traditionally used for elderly people. The 9-inch wheels have thermoplastic-resin spokes that radiate from the rim to the tread, curving to the left and right for maximum structural support. The solid design doesn't require air, and consequently can't be punctured - so, no more flat tires. Read More

Self-inflating tire keeps the pressure up for cyclists

By - August 24, 2011 7 Pictures
While it’s nice to hear that Goodyear is developing self-inflating tires for cars, where does that leave bicycle riders? Still pumping, presumably? Well, not if they’re running PumpTires on their steed. As its name implies, the PumpTire is designed to automatically pump air into the inner tube, using the compressive effect of the tire meeting the ground as it turns. Once the tube reaches the desired pressure, the pumping action ceases. Read More

Goodyear's self-inflating tire system could make air pumps obsolete

By - August 12, 2011 1 Picture
It’s important to keep your tires sufficiently inflated, both for the sake of the tires themselves, and in order to maximize the performance and fuel economy of your vehicle. The problem is that for many of us, we only think to check our tire pressure when heading out on a long road trip – if even then. With Goodyear’s Air Maintenance Technology (AMT), however, that shouldn’t matter. The system, which is currently in development, would automatically keep tires topped up to the proper pressure.

Study says 71% of European drivers need more air in their tires

By - April 27, 2011 1 Picture
With the spotlight shining on of hybrid vehicles, kinetic energy recovery systems and stop start functionality, it's easy to forget that a very effective way to reduce fuel consumption and cut emissions is right in front of us – air. A study recent study by tire manufacturer Bridgestone suggests that it's not only easy to forget, most of us do forget. The company checked 38,000 cars in 9 European countries during 2010 with results showing that 71% of the drivers were driving on under-inflated tires. Read More

An effective, environmentally-friendly way to break down old tires

By - November 10, 2010 2 Pictures
The world practically runs on pneumatic tires, but getting rid of them is an environmental nightmare. Apart from playground flooring material, running tracks for athletes and horses and unfashionable footwear, disposing of or reusing tires has proven to be extremely problematic (remember the Osborne artificial reef off Ft Lauderdale, Florida, made from old tires? It became an environmental disaster and had to be removed by the US Military). Now a scientist at the University of Basque Country, Spain, has used the process of pyrolisis to decompose and reuse the left-over components of pneumatic tires. Read More
