Perhaps the problem is that the people who used re-treads were replacing
tires that had worn prematurely die to low air pressure. Way too many
people neglect to check their tires regularly to ensure they are at the
proper pressure. Rubber tires are slightly air permeable and the air
actually escapes right through the sidewalls. Air also escapes from
valve stems and even through the cap. Last year I had a problem with a
tire. The low air pressure warning light would come on every week or
two. The problem turned out to be that the sensor was leaking.
