Tire PSI

My car came off the boat with 46, 47. Dropped it down to 36.

When I got a Pontiac G8 years ago, from Australia, they were over 50 PSI!

Makes sense. I never really looked into it too much. I'm planning on running thinner wheels/tires for winter, so I'll need to figure this out

Boyle's Gas Law.

I always wanted a G8, but was broke as hell when those came out.

Since I have the 305's, I'm experimenting with lowering the pressures a little at a time for more comfort. If I remember correctly, you want them to go up 3-4 PSI after driving around a while.

That's going to happen regardless of starting pressure. Wheels generate heat as they make contact with the road and spin, so they will warm up as you drive.
That's why the door sticker pressure is what it should be "cold"
But yes, if you want a little more comfort, slightly lower pressure can help at the expense of slightly increased tire wear

Had TPS system on my camper it was amazing the temps you would get at 62mph. Cold was 80# traveling hot day they would get to 102# . Later RJD
