Air pressure
Michigan mornings are cool these days.
I start in the morning at 30 psi. In the afternoon tire pressure is at 34 psi.
Is that OK or should I adjust down to 29 psi or so.

No, that's okay. Just on the off chance that you would need to drive the car in the early morning while the tires are at 30 lbs, I'd leave them there.
34 lbs is okay to drive on later in the day. I wouldn't want to drive on them over about 37 or 38, but 34 is okay.

I try to shoot for around 37 hot (around town) for optimal traction. This works out to around 34 cold, and somewhere around 42 on the track running hard. This was with my stock tires; haven't had a chance to mess with pressures much on the new PSS I just got.
I saw perfectly even wear on the first set running these pressures.

I would think that the center of the tires would have worn early at 34 cold.
You probably did save a few coins in fuel cost though.
