Thanks to all of the nice folks who responded to my plea for help re: 235,
etc. tires.

As I've mentioned to many of them, I probably was the victim of low
inflation pressure on the mains. I guess that after sitting for about 90
days waiting out the cold weather, I should have checked the pressures - but
didn't. After repairing the flat, I checked the other main and, sure enough,
it too was way down. My fault - it's still too cold here to handle a screw
driver (to take off the hub covers) without the fingers going numb so I did
an eyeball check - and got caught.

Many responders who've had similar problems have recommended upping the
pressure in the mains (from the manual call out of 42 psi) to 50 - 55 psi.
When this was done, the problem went away - so I'm going to try it.

Nonetheless, I'm still going to carry a spare tire and tube just in case -
as they're obviously made of Unobtainium. (At least that's what most FBO's
think, anyway).

Thanks again,

Dan Schaefer
