Bridgestone Bringing Run-Flat Tires to the Masses

Tire company rolls out replacement tire line-up.

by on Apr.08, 2014

Bridgestone is introducing a new line-up of replacement run-flat tires for a wide array of vehicles. No longer is the technology limited to high-end vehicles.

The owners of a Chevrolet Corvette and a Chevrolet Sonic may soon have something in common beyond the “bow-tie” emblem on their vehicles: each can wait up to 50 miles to change a flat tire.

Bridgestone is introducing a line-up of replacement run-flat tires for a broader array of cars and trucks. Several other tire makers such as Michelin and Goodyear have run-flat tires for performance-oriented vehicles, such as the Chevrolet Corvette. Typically, they are original equipment on these vehicles.

However, Bridgestone is the first tire manufacturer to offer the run-flat as a replacement tire in more than 30 different sizes, which will fit on a broad array of vehicles. (more…)

Those Underinflated Tires Could Kill You

Study links low tire pressure to sharp increase in crashes.

Today’s tires are engineering marvels, improving both performance and fuel economy, even if they tend to largely be ignored by motorists. But that’s a problem that also turn a tire into a killer.

A new government study warns that as many as one in 20 crashes could be linked to tire-related problems, with underinflated tires posing an especially high risk of causing a problem.

“Tire problems are inherently hazardous to vehicle safety,” said the report by the National Highway Traffic Safety Administration, which based its study on crash data covering a three-year period from 2005 to 2007.

The report found that underinflation was the biggest problem, with a tire 25% below its rated pressure three times more likely to be involved in a crash.

Part of the problem is that a low tire reduces the vehicle’s stability even under ideal conditions, but it also makes it significantly more difficult for a driver to maintain control in bad weather or during emergency maneuvers, such as swerving to avoid an obstacle in the road.


Do “Fuel Saving” Tires Work?

You can save $100 annually, according to the latest tests.

Old company but with the latest technology to save you fuel.

The problem with all-season tires is just that. By trying to come up with rubber compounds and tread designs that work year round, engineers trade off such things as maximum traction on dry pavement, or noise generated by the tread, or the best grip in snow. Moreover, early versions of such tires were mediocre at best.

Forced by fuel economy regulations, automakers have specified as original equipment a type of all-season tire known as fuel-saving to help improve ratings for quite some time. Tires with lower “rolling resistance”—the amount of force that it takes to roll a tire down a road—are more fuel-efficient than others, but trade-offs are made to achieve this.

However, replacement tires are not limited to an automaker’s requirements, and tire companies aggressively market attributes such as all-season grip and tread life with less emphasis on other areas of performance.

If you thought about it at all, a replacement tire choice was a compromise between low rolling resistance and other  attributes—such as good dry- and wet-weather grip for stopping and cornering.

Consumer Reports’  latest tests of two all-season, low-rolling resistance tires – the Michelin Energy Saver A/S and the Cooper GFE – show that they not only save gas, but also deliver good stopping and handling capabilities.


Give Your Tires Some Respect

Few things do more to improve safety, mileage, performance.

by on Jan.06, 2010

The right tires can make a big difference in performance, safety and fuel economy, especially on winter roads.

They’re the automotive equivalent of Rodney Dangerfield, but while tires typically “get no respect,’ they should, because arguably no single part of your car has a bigger influence over matters ranging from performance to mileage – and especially your safety.

Today’s car is a high-tech wonder, with some models featuring more than a dozen different computer systems onboard.  Yet the tire is decidedly low-tech, or so you might think.  In reality, rubber companies have invested billions into computer-aided design and manufacturing systems designed to improve the performance of those four black donuts at the corners of your car.

The latest designs last far longer than the tires of a generation ago.  They also achieve the seemingly impossible: giving you both a better grip on the road while reducing what the industry calls “rolling resistance.”  In layman’s terms, that translates into better mileage.

No Retreads!

In the wake of the Firestone/Ford fiasco, in which 280 deaths were linked to tire failures on Explorer SUVs, federal regulators ordered the use of tire pressure monitoring systems designed to alert motorists when tires lose pressure.
