Arlen Holder:   
      
   So rounded off we'll just say 270 sq. inch of area inside the avg. passenger   
   tire.  I think something was wrong with that online calculator I was using last   
   night to convert square mm to square inches.  For a similar tire I was getting,   
   if I recall,1,220-something square inches?  I suspected something was off!   
      
   So the air inside the tire inflated to 35psi is pressing down on each one of   
   those 270 square inches with 35 lbs of force. So a more sane 9,450lbs of   
   total pressure on the inside wall of that tire.  Probably closer to 7,000ish if   
   you consider that side of the rim which completes the inside of that total air   
   cavity at each corner of our daily vehicles.
