And no.... 5 psi overinflated is not worth worrying about. Heck, most folks here throw an extra 5 lbs in each tire just for the hell of it! There is no downside to 5-10 lbs over.
Underinflate? Yes, heat generation problems can follow. 5-10 lbs underinflated should be adjusted. Well, 10 lbs certainly, but 5 would have me wondering where the air went.
