Default Bridgestone launches new low rolling-resistance tire- to help fuel economy



What are low rolling-resistance tires? If you take two vehicles, one with conventional tires and one with low rolling-resistance tires, and free-roll them with no mechanical input down a slope, the one with low rolling-resistance tires will go further than the one with conventional tires with the same amount of energy input. Low rolling-resistance tires minimize wasted energy as a tire rolls. This is how low rolling-resistance tires contribute to better fuel economy.

Of course, there was a price to pay. The wet and dry performance of low rolling-resistance tires was typically worse than that for a similar conventional tire. Simply stated, they had less grip. And they would wear faster than a conventional tire.


Bridgestone recently launched two new low rolling-resistance tires the Ecopia EP422 for fuel-efficient vehicles and the Dueler H/L 422 Ecopia for SUV, CUV and light truck applications that incorporate technology that improves grip and extends tire life.


What do you guys think of the low resiting tiers? Just really cursious has anyone used them before?

Do low resiting tiers effect that much? Is it worth the crappier tread life and a worse grip..

Makes me wonder all for Fuel MPG is it worth it?

You rarely find a hybrid that has good handling anyway. Plus you dont normally go fast in a hybrid so handling wont be that big of an issue. The tire wear will not be too big of an issue since the money you will be saving from the better gas mileage will help towards a new tire.
