When inflating a tire to seat the bead, never exceed ______.

Bead seating requires enough pressure to push the tire bead over the rim flange, but not so much that the bead or rim can be damaged in a sudden burst. For most passenger-car tires, a conservative upper limit of about forty psi is used during bead seating. This provides enough force to seat the bead without risking a bead blowout or rim damage. Pushing higher than this increases the danger of injury and component damage, while too little pressure (like twenty psi) may not seat the bead reliably. Always follow the tire’s sidewall maximum and the equipment’s guidelines, but forty psi is the standard safe limit for bead seating.
