Fuel Consumption Depends on Tyres. Eco-friendly Tyres - the Secret to Fuel Efficiency.

Eco-friendly tyres help save fuel.. The secret is reduced rolling resistance.
The tyres look no different, but eco-friendly tyres use an advanced rubber compound
that offers less rolling resistance. Let’s demonstrate this secret with two tests.
Test1: First, We'll roll two rubber balls at the same time with the same force on a cone-shaped course.
Test2: Two cars with tires made of two different rubber compounds run with the same amount of power.

How can we sum up these rolling tests?
