[VAC] Re: Tire & Tire Pressure Questions

[Inlandrv@xxxxxxx]

Gerald J. A Goodyear Marathon load range "D" tire at 65 PSI is rated at 2540 
pounds each, for a tandem axle total of  10,160 pounds. That certainly is 
very far from being overloaded with any tandem axle Airstream trailer, ever 
built. "E" tires are rated at about 3100 pounds each, at 75 PSI. If you put 
"E" tires on the original Airstream wheels and air them to maximum tire 
pressure of 75 PSI, then you are also at the max rating of the wheel, at cold 
pressures. That's not be what would be considered "safe." Safe is usually 
defined in mechanics as never exceeding about 75 percent of a maximum rating. 
But, since some folks love living on the edge, and toss safety aside, they 
sometimes don't realize the personal liability they expose themselves to when 
they operate out of reasonable and prudent safety envelopes. Andy
