Doubt it.

About 15 years ago I heard of a company in a very hot climate that 
was experiencing numerous blowouts on company vehicles.  They called 
in "experts" from Firestone, Bridgestone, Goodyear and Yokohoma.  The 
consensus was that the cause was too *little* pressure weakening the 
tire.  The solution was to run *higher* pressures.  They recommended 
45 PSI cold on all passenger and light truck tires listed at 35 psi.  

The tire companies reasoned that the higher pressure would have very 
little detrimental effects, but low pressure was deadly - it could 
damage the tire, weakening it, and then it would blow out later when 
the tire got hot.
