[DeTomaso] Tire pressures, alternators

[David D Fisher]

Now that my car is on the road,  I've got a couple of operating questions for the collective wisdom of this group...
 
 
1) I'm running 17 inch tires  335 35  rear, 215  45 front.   What have folks settled on as optimal tire pressures?
 
2) I'm looking for a replacement alternator?   With the A/C, cooling fans, and lights on,  mine cant keep up.  Truthfully,  it doesnt charge at all unitl about 1500 rpm and then kicks out 75 amps, but if you are idling around from stoplight to stoplight the battery is just draining.   I dont see a regulator anywhere on the car, so I assume this alternator has it built in.
