Spare tire pressure

I've gotten in the habit of pumping the spare up to sidewall pressure rating. Caveat is that there's a pressure gauge in the car to reduce to normal when/if the spare is used.
Background: T4R is 'her' car, easy to get clubs/groceries/luggage in and out. She likes sitting up high too. On more than a couple of trips, I've gotten that phone call about the tire pressure warning light. 4 on the ground all read OK per the gauge. So when the car gets back home, the spare is the one that's triggering the warning light. Pumping it up to the sidewall pressure has eliminated the nuisance "alerts". And FWIW at near the end of life on the secod set of Michelins on the car, that spare has never been bolted to a hub. (probably jinxed myself saying that...) Even if she does have an incident and needs the spare mounted by the AAA driver, I'd rather have it a little overinflated than a bit underinflated.
My too sense.

I agree with Dr Bob. I got tired of the tire pressure warning light coming on, so whenever I add air to the spare I put it up at least 5 psi above the recommended pressure for the vehicle. If I ever have to use it I have a gauge on board to let it down to the same pressure as the tires on the vehicle.
