1Replacing Your Tires: Four Money-Saving Tips

Knowing when to change tires will keep you safe on the road

Even the most sophisticated braking systems won't work if the tires aren't gripping the road. Maintaining your tires and replacing them when necessary is vital to safety.

8GM partnering with tire researchers for better fuel economy

Starting next year, General Motors engineers will work with researchers at the National Tire Research Center in an effort to create safer and more efficient tires. The automaker has invested $5 million in the facility in Halifax, Virginia, which uses cutting-edge tire performance machinery to recreate real-world driving events.

16The two sides of Bridgestone's new off-road tire plant in Aiken, SC

Bridgestone is in an interesting position. On the one hand, the tire manufacturer wants to increase its green credentials with its line of Ecopia products. These are low-rolling resistance tires that improve efficiency by around five or six percent and are now available in 50 sizes that fit everything from hybrids to large SUVs. They're even used on all Nissan Leaf electric vehicles. On top of the Ecopia line, Bridgestone has big goals to reduce CO2 emission from its entire products lifecycle by

19Goodyear unveils self-inflating tires for big trucks

Goodyear has developed a new self-inflating tire for commercial vehicles. The Air Maintenance Technology system uses an internal pressure regulator to determine when the tire is low. When pressure falls below a certain parameter, the regulator opens to allow air into a pumping tube. Here's the cool part: the tube runs around the circumference of the tire, and as tire rolls, it squeezes the tube, effectively forcing air into the tire through an inlet. Once the tire is properly inflated, the regul

18Goodyear uses the old "surprise gymkhana road test with stunt driver" routine

It's a familiar tactic: if you want a customer to know what a car can do, you've got to get them in it and take them for a ride. To truly impress a customer, though, you've got to take them, *ahem,* for a ride. It works so well that NASCAR driver Carl Edwards recently did it with Ford engineers in a Taurus SHO – the very sedan those engineers worked on.

87Nissan's Easy Fill idiot-proofs tire inflation *UPDATE

Nissan is moving to make its Easy Fill Tire Alert system standard equipment on its 2013 model year vehicles. Taking the federally mandated tire pressure monitoring system to the next logical step, the Nissan system honks the car's horn when you've inflated your tires to the correct pressure. No more reading the tire pressure placard on the door jamb and hunting around in the glovebox for a pressure gauge.

27German researchers developing electronic tires that adapt to weather conditions

Even tires considered basic are the results of massive engineering and financial investments – a single tire can include up to 20 different kinds of rubber compounds and their constructions and build techniques are so mysterious that it's easier to get a tour of the White House than a tire factory. A new tire being worked on by a team of German engineers at the University of Leipzig, however, would be a Buck Rodgers-like leap in tire tech by incorporating changeable elements to alter the s

10Radar Tires debuts pink-wall radials to fight breast cancer

Radar Tires has initiated a new charity campaign to fight breast cancer. The Mobilizing Hope campaign is aimed at stirring awareness through various channels, including the Ring of Hope project, which features a limited-edition pink sidewall tire. Based on the Radar Tires RPX900 all-season performance tire, the rubber will initially be available in two sizes: 195/60R15 and 205/55R16. Radar Tires says that those sizes will fit a variety of popular vehicles, including the Mini Cooper, Ford Focus,

7Wim Delvoye's carved tire art is steel-belted beauty

It's a good thing we aren't fabulously wealthy, otherwise our domiciles would be clad in all sorts of clever automotive art. We're not just talking cheesy vinyl bench-seat sofas and engine-block coffee tables, either. We like to think our taste elevates above some of the more common automotive décor we've seen. Take Wim Delvoye's intricate tire carvings, for example. Each piece is filled with exquisite detail and is hand carved. Untold hours have been sunk into each piece (we have to imag

9Follow-Up: Michelin, Avon, Pirelli bid for F1 tire contract

With Bridgestone's hegemony on supplying tires to Formula One set to end this year, rubber companies are lining up en masse to grasp at the opportunity to take its place. We recently reported on Michelin's ambitions, but the French tire company isn't the only option being considered. According to Sam Michael, technical director for the Williams team, the options have been narrowed down to Michelin or Cooper Avon. Pirelli, however, has also announced its interest in returning to the championship.

18Michelin considers returning to F1... with some conditions

A tire war could be sparked in Formula One within a couple of seasons if Michelin gets what it wants. The French tire manufacturer ceased its participation in the sport after F1 moved to a single-supplier formula, selecting Bridgestone as its partner. But with Bridgestone set to leave at the end of next season, team bosses reportedly met with Bernie Ecclestone in Malaysia on Friday to discuss potential replacements.

72Report: Quebec drivers face hefty fine if they don't drive on snow tires

Ah, Quebec. Beautiful women, beautiful city, fantastic food. But there is a dark side. No, not poutin and steamies. We're talking about the language police! Answer your phone incorrectly, write something in English more than 50 percent the size of the equivalent French phrase or – worst of all – if you forget to bother with French at all, it's off with your head an annoying fine. Joining the Québécois language police are a new group of cops – the tire police.

AddSEMA 2009: The geekiest thing we've found so far

Tire pressure monitoring systems. Not the sexiest thing here at SEMA, but bear with us for a few minutes to geek out on one of the coolest things we've seen at the show that doesn't involve a whole vehicle.

AddThe European Union is studying green label for tires

The EU is readying legislation that will label tires according to their impact on the environment. The idea is to create a label that would spot three values, two of them inspired by current energy efficiency ratings of domestic appliances:

19Self-inflating tire technology captures innovation award

The Tire Technology of the Year award, handed out at the Tire Technology Expo in Hamburg, Germany, has been awarded to the creators of the Self-Inflating Tire at Coda Development.

26Titan Tire ships world's first 63-inch tire

Remember in the first Crocodile Dundee movie when he gets mugged in New York City and Sue says "He's got a knife," and Dundee says, "That's not a knife, this is a knife," and then he pulls out a beast-killing monstrosity of a blade? Well, that's what the folks at Titan Tire are saying right now about every other -- smaller -- tire in the world.
