Tire pressure change

[Plasboy]

im thinking I read somewhere that Chevy had changed the recommended air pressure for at least some Corvette models. Can anyone confirm this? Different than from 2015.

They did increase the tire pressure from 30 to 35 PSI, perhaps only for the SR model, around 2017, but believe it is back to 30. Whatever they did or did not do when, go to the driver’s door sticker and follow that.

Corvettes with the 19/20 inch wheel combination have always been 30 psi. Ones with the 18/19 inch wheels were 30 psi up to 2015. In 2016, I think ,they switched that size to 35 psi. The guess is to try to improve mileage a bit, but GM never gave a reason. In either 2017 or 2018 they dropped the 18/19 inch wheels completely. All Corvettes after come with the 19/20 rims and 30 psi.
