Please add air to make it 38 cold. Best for mileage comfort and wearAs a couple other people mentioned, check your tire pressure before you leave the dealership. My tires were all in the 42-46 psi range. I aired down to 38 psi and by my first fill-up I was back to 44-48 psi. I aired back down to 38 psi and that held until I got home 9 hrs later.
Should not be 38 after driving.
Heat, elevation gain adds pressure.
