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?
