What are the recommended tire pressures for a 1989 Chevy Chevette?
That was my first car when I was in highschool. I’m surprised you have that car still running. However, the tire pressure is based on the type of tire you have. It can be different. But, for most cars, the average tire pressure should be about 35 psi, but not lower than 30. Look on the tire to see the recommended and max tire pressure. It’s printed on the wall of the tire.
