Did They Do a Good 

 Job the Last Time They 

 Vulcanized Your Tires? 

 It Is By No Means a 

 Simple Piece of Work 



First the tread should be stripped back 

 several inches from the rupture as here 

 shown. Next "step" back the inner plies

If the plies aren't "stepped" back; that is, 

 cut off one behind another stair-step style, 

 all the breaks in the fabric come in one 

 place. There is no interlacing of layers; so 

 a blowout can very easily occur again 



Be wary of the tire-vulcanizing job that is 

 simply a corking-up of a hole with a rubber 

 plug. It will not hold for long, nor will 

 it ride smoothly. At right : Carefully 

 smoothing up a tire before vulcanizing it
