Hi folks... I’m new to the “forum” world. I just bought an ‘05 ENVOY with 40k miles. It’s practically brand new. My question is this: why is the front tire pressure 30psi and the rear pressure 35psi? Makes no sense to me. I’m not a car guy at all. Won’t even pretend to be. I know how to start it and fill it with gas. I’m that guy. Sorry.
