My problems with low tire pressures start to appear long before bottoming out the tire on the rim under impact occurs, namely the handling goes to crap first. I cannot stand mushy tires that can’t carve a crisp line and squirm under hard efforts. I like the bike to feel athletic, which is why I always set pressure by inflating to max indicated and then backing down until the bike starts to lose handling sharpness.
