Steve--

I found that on our Miata, after 25k miles, the tires were wearing on the 
edges more than evenly, so I bumped the tires up to 30#.  We are up to 45k 
miles now, but will have to wait until the tires are replaced, probably this 
summer, to find out how 30# effects the wear pattern.

There is an old drag racers trick to find the correct pressure for max. 
traction by doing burn outs and examining the rubber pattern in the road.  
Unfortunately, this is not enough pressure to keep the tires from rolling 
while cornering, which is not a drag racing thing.  This method doesn't work 
very well on independent suspensions either.
