Before assembly of the rim wheel	Apply rubber lubricant to bead and wheel mating surfaces, unless the tire or wheel manufacturer recommends against the use of any rubber lubricant.
When using a tire changing machine	Make sure the tire is inflated only to the minimum pressure necessary to force the tire bead onto the rim ledge while on the tire changing machine.
When using a bead expander	Make sure it's removed : – Before the valve core is installed or – As soon as the rim wheel becomes airtight (the tire bead slips onto the bead seat).

Note:

You shouldn't inflate tires above 40 psi to seat the bead.

Make sure tires aren't inflated when any flat, solid surface is in the trajectory and within one foot of the sidewall.
Make sure employees stay out of the trajectory when inflating a tire.
Make sure, when inflating tires, that the inflation pressure stamped in the sidewall isn't exceeded unless the manufacturer recommends a higher pressure.
Make sure tires aren't inflated above the maximum pressure recommended by the manufacturer to seat the tire bead firmly against the rim flange.
