There isn't a correct tyre pressure for a given bike.
there is a correct range of presures for the combined weight of bike, rider, and any accessories, and for teh type of riding you do, and the type of tyre you have (tubeless are usually run at lower pressure than tubed tyres, and wider tyre are usually also run at lower pressure than narrower tyres).
So if you can give us your weight, the weight of the bike and the type of riding, somebody will be able to give you the range it should be within.
