For road bicycles 7 bar is just “normal”, 8 and above isn’t unheard of.
A guy once asked if I was crazy when I was pressurizing my hybrid bike to 6 bar, and I just pointed to the sidewall where the rating said 4.5-6.5 bar. The range is wide because the pressure you should use varies depending on what you weigh, and how you want to balance rolling resistance vs comfort.
And even then the safety margin on bike tires is more than double the max rating, so it’s perfectly safe to go a full bar over if you want.
Any car tire.
