<VV> High Tire Pressures

[Ron]

I don't understand the fetish for high tire pressures as GM steadfastly maintained that 15 and 26 were the correct pressures.  Even my modern Solara specifies 28 for any speed up to 100 and then raises it to 36 only if driving continuously at over 100.  Has anyone been driving their Corvair continuously, like all afternoon, at over 100?  I'll stick to my 18 and 28 and consider it only mildly over pressured.
