The net force on the tire is the difference between the force due to the tire pressure and the force due to the atmospheric pressure. The force due to the tire pressure is 30 psi * 2 square inches = 60 lbs. The force due to the atmospheric pressure is 14 psi * 2 square inches = 28 lbs. The net force is therefore 60 lbs - 28 lbs = 32 lbs.
