Leaky inner tubes come from a variety of causes. It may 

 be that the valve plunger is worn or sticks; the lock-nut at the 

 base of the valve stem may work loose; or running flat may 

 honeycomb the inside of the casing with tiny holes. In running a 

 tire soft or in changing it along the roadside, foreign substances 

 get in between the rim and beads and work around next to the 

 tube. Particles of rust off the rims also cut the tubes oftentimes. 

 Though these holes are, as a general rule, too small to be seen by 

 the naked eye, yet under pressure they will leak enough air to 

 let a tire down fifteen to twenty pounds pressure in a week's 

 time. — Miller News Service.
