Something not mentioned here is that racing tires use a very different compound than passenger tires. Racing tires are geneally quite sticky. You can't really compare the two.

The point of this thread was not to say that there is absolutely no difference in traction in relation to pressure (an oversimplification) but that the difference is insignificant for our purposes. There is not a big safety concern with running max sidewall compared with mfg suggested inflation pressure.

Data to prove or disprove this is always welcome.

The tread width issue is not particularly important to this thread because narrower is better for aero and an increased hydroplaning speed.
