Since I've owned Fieros along with the Corvairs I was always curious why the Corvair has such a great pressure differential between the front and rear while the Fiero doesn't. Both cars have about the same weight distribution front to rear. I posed the question on the VV forum and got some interesting results but one response really made sense to me. I've posted it on my website. Tires Pressure

But remember that when Jim Hall wrote that artical, Radial tires weren't in use. Radials will require less tire pressure differential although some is still desireable.
By the way, have you owned any Vega's? You would have all of GM's underdogs.

I made the radial tire argument but everyone says it doesn't hold water (or air!!)

Vegas? Holy smokes!! In the late 70s I used to buy wrecked Vegas for $100 or $200 and fix them up and sell them for $1,000 or $1500 depending. Sometimes I'd get one I liked and would keep it for a couple years. My wife had a love affair with a Kammback we converted to a GT and put a cool two-tone silver paint job on. It was a cool little car.

I don't know what it is about me and orphans!!

BTW, do you know where we can get our hands on a Cosworth Vega for cheap??

The general thoughts in the Corvair Club is 20 pounds front and 3o pounds rear with cold tires...This is about 5 pounds over the factory figures.Thats what I run in my radials and seems to work out fine.The most important thing is to have about 8 to 10 pounds more in the rear than the front.

That seems to be the secret. I have always run 22 front and 34 rear and have had no ill effects - and I drive way too frisky!!

Read Ralph Naders book, "Unsafe at any Speed" the difference in pressures had to do with GM trying to correct under/oversteer problems. In 1961 I owned a 1960, traded it for a 62 coupe with PG and Monza engine (new),the station I traded at then just put air in the tires they did not adhere to the owners manual. Between the two cars I had over 60,000 miles on them loved the rear engine configuration in our snow and ice. Never had a problem of any kind and the cars were pushed and pushed hard.

They really do go well in the snow. We lived in Colorado for several years and I drove my Corsa to work every day. It never ever got stuck. I had over 260,000 miles on it before it met it's demise in the summer of '04.
