sorry if it seemed I was picking on you, BklynG, because I wasn't. This has popped up on the Giulia forum so much that it's turning into a new owner checklist type of thing, and very few (if any) of the people who have encountered it are first time owners.
It ABSOLUTELY should be done by the dealers, and it is incomprehensible how many don't.
No, your tire wouldn't pop - but it will give a harsh ride, have poor traction, and wear excessively in the center if left too high for many miles.
People should not have to check their tire pressure, oil level etc when picking up a new car.
People should know to read their owners manual so they know about their car, and should know to consult it when they get a warning (idiot) light on their dash, etc etc . there is plenty of information in the manual, and on Alfa's youtube channel, which others are constantly pointing people to when they ask questions on forums.
the tire pressure warning light is for low pressures, apparently not for high ones, as it does not light up.
