<VV> Tire size vs air pressure survey

[Sethracer at aol.com]

In reality, there are only two problems with tire pressures and Corvairs.  
First, you must run sufficient rear pressures to carry the increased load 
that  the rear-engined car imparts on the tires. Second, the front tires are 
so  lightly loaded (dependent on tire size) that it is possible to run too 
much air  in the front tires, resulting in the reduction of the contact patch 
to the road,  and resultant poor front traction. Life with the Corvair tire, 
whether for  street use or racing, is a constant search for enough, but not 
too much,  pressure - usually at both ends of the car at once! With 
properly sized radial  tires, I have been happy with 24 in the front and 32 in the 
back. It is a  good balance between ride and wear.  Front pressures  are 
subject to change if trunk is filled up.

We all  know what Chevy put on the glove box for OEM tires, but what do 
you run  with larger tires, or stock sized radials?

For years with 175 and 185  width radials, I ran 25 front, 35 rear, or 
close to those numbers. I  recall a period of 22 front and 32 rear.

On my daughter's LM, with  205/65R15 we have been running 25 front, 32 
rear or so. Wear seems fine  (even) and steering effort is nice. These 
are on S-10 rims, great look  (needed slight machining to fit).

Note all these numbers are for street  use, not racing. For auto crossing 
stock wheels/tires I always ran 30 psi  front and 40 psi rear.

So, what are you guys wearing as air pressure  numbers?
