If high tyre pressure is faster due to a decreased contact patch and therefore less friction, why are softer compound tyres faster than hard?
Also why is a thinner tyre faster than a thicker one when the road-rubber contact would seemingly be the same

I think rolling resistance is determined by the amount of energy lost in deforming the tyre, would answer most of these questions. Smaller contact patch = less deforming, soft tyre= supple tyre conforms easier, thinner tyre = less deforming.

I'll wait for tester to explain why I'm wrong.

Yes I thought that but then if a harder compound, thicker tyre deformed less because its much firmer, wouldn't that be less of a loss in energy?

Is an inner tube at 120 PSI within a thin tyre actually firmer than a tyre entirely solid, made from the same rubber compound?
