What is the tyre’s rolling resistance?

Tyre’s resistance has customarily has been estimated through SAE (Society of Automotive Engineers) test method J1269. It measures the power required to roll a tyre against a dynamometer at a fixed speed of 50 mph.

There are in excess of 1,300 cars and light trucks in the Bridgestone line alone — and possibly, everyone could have an alternate moving opposition. The vehicle material is the main consideration, yet development, size, and even track example can have an impact.

At roughly one hour for each moving opposition test, this adds up to 3,900 hours — or more than a half year — just to run the Bridgestone brand. This clarifies why these qualities are assessed. However, plus tyres are not tested for rolling resistance.
