Tire runs flat every 30 days @Nick C: Had no idea about that - I've seen numerous ruined inner tubes thrown away and presumed all car tires have those. I learned something today.

Tire runs flat every 30 days @Nick C: I wlways thought a tire consists of two layers - the harder one which is cut out where it is in contact with the rim and the soft one which is like a donut and actually holds compressed air. Where am I wrong?
