If the tire PSIs were correct, the "problem" was not significant.
The front and rear tire PSIs were significantly different.

"The Corvair relied on an unusually high front to rear pressure differential (15psi front, 26psi rear, when cold; 18 psi and 30psi hot), and if one inflated the tires equally, as was standard practice for all other cars at the time, the result was a dangerous oversteer"
