One thing I remember about our '65 Corvair was how touchy the steering was if the tire pressures weren't right, which they often were after oil changes when some unknowing mechanic would put too much air in the front tires. Seems it wasn't coomonly known that they needed high pressure in the back and low in front, like 32/20 or something like that. If they were high all around, the steering was very light and touchy, and kind of squirrely in crosswinds.
Hello, We always kept the 62 Corvair at the normal tire pressure as listed from the dealer. The lightweight car did its best to go straight, but the so cal cross winds on the coastal highway called "Santana" winds does blow quite fiercely and that always shoves any car, let alone this Corvair coupe a slight bit. Any car with higher pressure in front tends to have a wavy, light handling vs normal tire pressure. The rear tires had to hold up the motor and required a normal tire pressure and level stance for best driving. Don't get me wrong, we liked the little car as it took up less space in a small two car garage. It got great gas mileage and was a reliable car to do short errands or visits to friends. It may not be a long distance road trip vehicle as it did sit low and others towered over the small car. But, every summer, my wife drove it up the local mountains to Big Bear Lake for a vacation before school started in the fall. Jnaki My wife bought the car as a teenager and by the time we got married, the car had seen a lot of local miles. But, it did run well. I just kept the car running as best as possible. After two incidents away from our local neighborhood streets, it was time to sell it, so we gave it away to a needy uncle. YRMV We never heard of lowering the tire pressure in the car's stance and handling, but, definitely, never in the back. There was a lot going on in the rear with the suspension and drivetrain. It was a different model in 1965. But, perhaps, it was 22-28 in front and 28-30 in the rear. That seems to be rolling around in my head... more in the rear tires.
