I don't think that regular automotive rubber valve stems are designed to run at 180 degrees for hours on in.
I understand that the "overall" consensus is to run the higher tire pressures,
a couple of years ago my wife and I took a trip that was to last several months
we were fully loaded and I was pulling a Bushtec trailer,
almost immediately I started noticing my rear tire running very hot (48/42psi) this continued for several days
until I brought the tire pressure down to (42/37 psi)
one of the things I noticed was the "sway" in the trailer was gone
and my entire "rig" handled better,
I know this subject has been greatly debated and my intention is not to re-open this debate,
I'm going to run my tires at the lower pressures,
y'all can do whatever you want to.
Rather my question to Wolfgang or anybody else running the smartire system is
have any of y'all ever tried running at lower pressures
and how does this affect the related tire temperatures?
