Depends on your weight, what surfaces you're riding on, how you carry your weight on the bike, what sort of suspension the bicycle has (or doesn't have), and even the designs of the particular tire and rim and inner tube.
To get some sense for a baseline, though, what's your bike+rider weight? What's your gravel like?
