"Tires is what wins a race." That was the lesson Harry tried to teach Cole in the stock-car classic Days of Thunder. "If we can't figure a way to run so you don't melt the damn tires, we can't finish a race." How right he was: every NASCAR driver knows that having the right tires can mean the difference between a checkered flag and a DNF, but now the White House is embracing the same message to educate the public about safety and fuel efficiency.
Low Rolling Resistance Tire
Yellowstone National Park's most famous attraction is called "Old Faithful." Now, Michelin says its tires make their own claim to dependability inside the oldest national park in the US. Indeed, the tiremaker has donated more than 1,400 tires to the National Park Service since 2008, enough so that the NPS has saved around $300,000 in annual expenses for its 800-vehicle fleet.
Unless we're talking about tires used for specific conditions (snow, summer, off-road, etc.), we imagine most new car buyers don't think twice about the rubber on their ride. J.D. Power and Associates does, and it recently rated consumer satisfaction for the top tire brands in various vehicle segments, and it found that Michelin was consistently at or among the top-satisfying tire brands. As a part of this study, it also found some interesting data regarding two growing types of tires: run-flat
Tires get overlooked in the headlines about fuel economy and CAFE standards, which is a little odd. After all, a car's tires are the only contact it has with the road, so more efficient rubber means more efficient use of fuel, and even tiny gains spread over the huge number of road-going vehicles can translate into remarkable overall gains.
If you've been waiting awhile to see the GreenGT motorsport race car make it to race tracks, you can wave the flag next year. What started out as a black and white electric racer in 2009 – then got green accents in 2010 and 2011 – has now become the GreenGT H2, a hydrogen fuel cell-powered race car featuring electric power train technology. Dunlop Motorsport will be part of the team, and is developing tires to drive the technology forward.
Bridgestone has announced the expansion of its fuel-saving Ecopia EP422 low-rolling resistance tire lineup from five to 29 sizes, ranging from 15- to 18-inch tires sized specifically for vehicles like the Toyota Prius, Chevy Malibu, Nissan Altima and Honda Odyssey.
Recently, Consumer Reports conducted a survey of car tire buyers and discovered that a remarkable 95 percent of consumers were satisfied with their shopping experience. CR also found, though, that less than half of tire buyers researched before purchasing. When "so much is riding on your tires" you'd think that a few minutes devoted to investigating the proper running gear would be time well spent but, according to the Consumer Reports' survey, buyers often decided to skip the legwork and mount

Of all the tips and tricks that are known to save fuel on modern-day cars and trucks, one that often gets overlooked is getting the right set of tires mounted up. Of course, nobody wants to use an inferior set of tires in the hopes of saving just a wee bit of gas, so Consumer Reports decided it was high time to line two of the biggest players in the rubber industry, Cooper and Michelin, against one another to see who came out on top in the low rolling resistance category.
Low rolling resistance tires usually bring fuel economy at the expense of noise, comfort and performance. Something's got to give, and to make the doughnuts turn more easily, engineers have to crank up the amount of silica in the tread formulation, resulting in noisy, wimpy tires. Goodyear's new Assurance Fuel Max tire is a way to have your cake and eat it, too. The Assurance Fuel Max has a new tread compound designed right down to the molecules to deliver a 27% reduction in rolling resistance w
