I'm going to jump in this tire pressure discussion. Late, I know. Due to the months spent on a ship tied down, the tires are inflated to 48 psi so they don't flat spot.
High tire press. Keeps the tires cooler, with less rolling resistance and less wear.
The door sticker PSI represents best road feel, bump isolation, and comfort.
Running higher up to the cold tire press. listed on the tire is safe, better for the tire, mileage and power.
I run my Chevy Cruze at 45 psi. A more "sporty" ride, tighter handling and more power and fuel economy.

Got a Trax coming by July 1st. I'll experiment with slowly increasing the tire press. on it to find it's place. Won't be at 32 psi.

Flate rate is why tire press. is not checked during the PDI at the dealer. A PDI is a big $$ maker for techs. Pays 1.2 hours, can burn through them in 15 min.

My 2024 Chevy Trax activ came with 48psi of pressure in all four tires. Should have been checked at the dealership during pre-delivery inspection, but it wasn't. I put the air pressure to factory recommendations 36PSI front, 32PSI rear.

In my opinion the car rides way smoother at the factory recommendations. 48PSI makes for a rough ride.

There has also been reports of tire blowouts. My opinion, this is due to high tire pressure.

I personally feel if higher tire pressure gives you better gas mileage, it still isn't worth the trade off for the ride!
