Jim. More pressure equals more grip.  Who taught you that?  Not even  close dude.  More pressure causes less grip thus why overinflated tires wear out in the middle.  Lower pressure makes more grip. That's why top fuel cars run 8 to 12 lbs and why they screw the tires to the rim. Because there isn't enough pressure to keep the rims from spinning inside the tires. Pressure and handling are all about sidewalls maintaining shape and the transfer of weight.  Michael in savannah

 Within reason, more pressure = more grip, better steering response and sharper handling

I experimented with my car when it had 7's and 8's and found that about 3-4 lbs more in the rear was best-- I used to put them up to like 31 front 34 rear and they would slowly lose air over a few months but maintain roughly the same ratio
..
More difference between front and rear increases understeer / makes the car less likely to spin.? Low front tire pressures gives you lousy steering response and worn tire edges.? The brand of tire should not make any difference, assuming you have similarly designed tires on front and rear.

I believe there are some US owners manuals that suggest having more pressure in the FRONT.? I tried that once just to see and scared myself -- definitely not the thing to do.? The very idea of that is idiotic-- you need more pressure on the end of the car with more weight.? 

However, the above assumes your tire sizes are not wildly different. People who run 225 fronts and 335 rears have to run lower rear pressures to prevent the center of the tread from wearing early and also to prevent excessive understeer.??

I need to know what the recommended tire pressure is for Toyo Proxes 4's and 
ST's mounted on 15" factory 8's and 10's.
 
thanks in advance.
