So, I just checked my tire pressure for the first time. LOL, 60 PSI! I was like LOLWUT are you serious? Sure enough, it was right, all 4 were at 55-60PSI. Door sticker says 34. I pumped them all down to 34 and the ride quality on the highway improved by leaps and bounds, so much smoother now. Seriously, why would they send it from the factory at 60PSI? that seems pretty ridiculous.
check your stock tire pressure

Now we see why those cars get good gas mileage! Less rolling resistance! LOL
Funny, my 07 Mazda 3 was the same way when I bought it. Drove it home from the dealer with 60 psi in all the tires.
I thinks its to prevent tire flat spotting and rim damage during shipping.
Sometimes the dealer forgets to reset the pressure. I've seen this a lot on new cars.

60psi can get dangerous depending on how it get's outside. Good thing you checked it!
Probably because the 14 year old kid doing the PDI forgot to adjust it.

Over on the priuschat site, it seems like you are not part of the cool club unless you are running at least 40 psi LOL. Running tires past the cold sidewall max is not uncommon at all.
But yeah, it sounds like someone forgot to adjust the tire pressure upon PDI.

Its hot outside, likely hotter than japan. Pressure will go up.
Who knows if/how the port and dealer checked it.

Maybe the kid prepping the car filled them by sight - stopped filling them when they appeared round!
Same deal when I get tires installed. They're always overinflated. Some techs just have a phobia about tire pressure gauges, I suppose.
The Mazda's from Japan always come overinflated like that. It is to prevent flat spotting while the cars are on the boat ride across the Pacific.

This is correct.
USUALLY they reset these right at the port, but on occasion they miss some and the dealers are not great when PDIing anyhow.
I know with VWs that they install hard rubber blocks in the springs to prevent damage to struts and other suspension components and they are supposed to be removed at the port or at the dealer, and sure enough you'll get customers picking up their brand new VW and as soon as they drive it off the lot they come back with in half an hour complaining of a bone jarring ride in their new car.
"It didn't ride this hard during a test drive of the same model"
---"um yes they didn't remove the shipping blocks from your suspension during PDI, we'll take care of it, just a few minutes". LOL

A few of the first things I do when I get a new (or used, new-to-me) ride: 1) Check tire and spare tire pressures; 2) Check the air valves' threaded inserts for tightness; 3) Order a backup wheel lock key or socket which I'll keep at home in case I or a mechanic misplaces the original; 4) LED flashlight, of course, and 5) Loosen all the lugnuts and then retighten them with a wrench no longer than the spare tire wrench in the trunk. If I retighten them with a 12" long wrench, then I know I can loosen them in East Dustville at midnight with the 12" OEM spare tire wrench.

It depends on the type of TPMS used. Some only scream if the pressure falls below a certain value.

Tires are inflated to ~ 50-60 psig to get the bead to seat and they are shipped to the dealer that way. The dealer is supposed to reset the tires to the recommended pressure as part of the pre-delivery inspection. I suspect that at many dealerships, that responsibility is given to the wash boy, who does a walk-around and says" it's ready to go"

True, I could easily see that happening. In my case when I bought my Trailblazer I drove it for about 10 miles before writing a check. It handled and rode nice - obviously or I would have walked away.
Before they gave me the keys they had to "detail" it. On the trip home I noticed the handling was terrible - it felt like I was driving on ice and it rode like a tank.
So I stopped and checked the tires - all of them were about 60 psi. After bleeding down to the recommended 30 front 35 rear, the ride and handling returned to what it was at the test drive. When I called the dealership they said they would "talk" to their staff - which I took for code for "We will file it in the circular file."
