You can create a list variable for selection field and on create / write method append your list in that variable which will add the value to the selection field.

Try following code:

POSITION_TIRE = [('pos_1', 'Posisi 1'), ('pos2', 'Posisi 2'), ('pos3', 'Posisi 3'),
                 ('pos4', 'Posisi 4'), ('pos5', 'Posisi 5'), ('pos6', 'Posisi 6'),
                 ('pos7', 'Posisi 7'), ('posa', 'Posisi A'), ('posb', 'Posisi B'),
                 ('posc', 'Posisi C'), ('posd', 'Posisi D'), ('pose', 'Posisi E'),
                 ('posf', 'Posisi F'), ('posg', 'Posisi G'), ('posh', 'Posisi H'),
                 ('posi', 'Posisi I'), ('posj', 'Posisi J'), ('posk', 'Posisi K'),
                 ('posl', 'Posisi L'), ('posm', 'Posisi M')]

class TireDetail(models.Model):
    ...
    position_tire = fields.Selection(POSITION_TIRE, string='Posisi Ban')

POSITION_TIRE.append(('xyz', '123')) # append the value to the selection field in create / write method
