Re: [RC] Truck/trailer tire ? - Heidi Smith

My truck tires say they should be inflated to 80 lbs, the trailer's to 60.
Yet my hubby, who is wonderful but doesn't know anything about autos or
fixing ANYTHING, says that I should not inflate the tires that high.  That
I
should leave the truck tires at around 60 and the trailer's at about 50.
Now I've had about 6 blow outs in as many years. The last one, Thursday,
the
truck tire still had tread.  The side walls disappeared and the
steelbelted
tread-part was all that was left.

Keeping in mind that I live where it can get to 95-100 degrees and the
asphalt is hot enough to cook eggs,  how high should those tires be
inflated?


They should be inflated to the manufacturer's specs.  If they are
underinflated, as yours have been, the sidewalls will flex too much, will
overheat, and will do exactly as you describe.

FWIW--the majority of flats that I've had, other than picking up foreign
bodies (nails, etc.) have been due to slow leaks that I've ignored, hence
causing underinflation.  And yep, those are the ones that really
disintegrate the tires....
