Leave the "Max. Cold Pressure" figure off the tire sidewalls period, since   
   more than half of drivers, vehicle owners, and even supposedly "ASE Certified"   
   mechanics first look there for what to adjust tire pressures to. Not kidding,   
   leave it off!   
      
   Instead, next to the maximum load weight in pounds & kg, inscribe: 'REFER TO   
   VEHICLE MANUFACTURER TIRE PLACARD OR LITERATURE FOR APPROPRIATE COLD TIRE   
   PRESSURES' on the tire sidewall, so as to remove any doubt.   
      
   The bursting inflation on tires made since the '90s is probably 50-100psi   
   above any pressure the car makers are likely to specify anyway, so why list a   
   Max. Cold number, since it's not near the bursting pressure anyway.
