Rolling resistance X Temperature

Rolling resistance X Temperature

Rolling resistance X Temperature

(OP)
What is the reason for drop in rolling resistance coefficient with increasing tir temperature?

Quote (Roberts, "Effect of temperature", p.59)

For a rise in temperature from 30 deg. C to 70 deg. C the rolling resistance decreased by 20-25%

RE: Rolling resistance X Temperature

The way I look at this is that the internal friction is reduced by the higher temperatures. The higher temperature "lubricates" the long chain hydrocarbons and allows them to flex more easily.

RE: Rolling resistance X Temperature

Instead of this presentation, plot the reciprocal of these two functions vs. each other with markers at each mileage increment. Then the relationship is more easily cogitated.

RE: Rolling resistance X Temperature

Exactly, the hysteresis energy loss is minimum
