There you can see the difference in rolling resistance what higher tire pressure does, and it sure does help. |
To completer this picture we need to know
what affect inflation pressure has on both traction and wear.
Further, that graph is for a particular tire under a certain load. When tires are tested according to standard conditions a good RR tire will get less than 6.5 N/kN (EU Rating of A) = 0.0065 on that graph - and a bad one will be worse than 10.6 N/kN (EU rating of E) = 0.0106 on that graph. That's a 60% difference.
Be careful with this data.
