As for running at a low 25psi. That will really hurt performance, mileage, and likely tire life.
I'm for tuning the suspension the other way. Increase pressure until abnormal center wear would become apparent.
This way you keep the most contact patch on the road.
It stays to the road better (more air pressure).
The sidewalls are stiffer (Better handling/less rollover).
Less rolling resistance (better performance & mileage)
Much stabler & more predictable handling.
Better road & steering feel. I was shocked to that I had to drop the pressues this low to get the "feel" i was looking for. In my turbo miata I ran 31/29 and 33/31 f/r with 205/50/15 RE-71's on pannasport fs15's and that car bairly weight 2500 lbs with me in it!. I'll try do some messin around with it this weekend and see where the pressures end up. But, FWIW, i've put 6,000 miles on the re-71's at the above mentioned pressures and the rears were bairly worn, but VERY evenly (i checked them when i rotated the tires two weeks ago). The fronts went through about 70% of the tread (lack of traction with the stock shocks/springs) with the inside edge showing the most wear and the center and outside showing uniform wear. And these are cold tire pressures by the way.
