   Re: Suuggestion For Passenger & LT Tire

   Arlen, Xeno:   
      
   Just to be clear: My concern about "maximum pressure" in a tire has nothing   
   to with mounting/seating pressure.  But everything to do with which source   
   people(like my younger self!) went by, and continue to go by, when adjusting   
   the tire pressures on their daily drives(to work, school, church, vacation, the   
   store, etc.).   
      
   And has been suggested here, if not implicitly, that the actual bursting   
   pressure   
   of a tire is, depending on its size, and probably rate of inflation(how   
   quickly air   
   is put in it) is at least 50psi HIGHER than the 'Max cold pressure' stamped on   
   the   
   tire.  If not even 100psi higher than that marking.   
      
   There is a huge public misperception that if you inflate to even 1psi(6-ought   
   kPa)   
   beyond that Max Cold designation, you're inviting an explosion - either while   
   filling the tire, or back out on the road - of that tire.  And that has been   
   proven,   
   in many ridiculous YouTube videos, not to be the case.   
      
   So for just those two reasons:  Driver/consumer/mechanic ignorance(some mechs),   
   and the actual astronomically high burst pressure, I see NO REASON to list a   
   "Max Cold Pressure" on tires designated for non-commercial private   
   passenger(and   
   *some* cargo) use.   There is a gray line there, because some official agencies   
   (police, medical) and commercial entities(liveries, cab cos.) do employ many of   
   the same vehicles, or variants of, as do the public.   
      
   Victoria and Taurus Intercepts, for example.  Customized versions of the same   
   workaday large vans we see driven around by self-employed plumbers and other   
   contractors.  How do we ensure those operators aren't over- or underinflating   
   their   
   tires?   
      
   Now I'm in the States, where knowledge is, at least over the last four years,   
   NOT   
   cool, and ignorance reigns supreme, sadly.  So I don't know if this whole   
   'door sticker   
   vs tire' pressure is an issue just here, or if such debate rages on as much in   
   other   
   countries.
