. Bob also checks the tires when we are sitting and can inflate them if needed. Very handy.
Linda, i found out the hard way that this practice wont work with the supper single tires,
the SS tires needs to be inflated to 120 Psi.
and the truck only provide 125 before the valve kick in, and drop the system to about 110.
by using the tool, i can only get the SS tires to hold about 110 - 115 at best.
i now carry the hoses as an emergency tool.
also at many fuel islands, the PSI is not high enough, and the air is full with vapors,that becomes a problem in winter time as those vapors iced inside the tire, or can open the tire valve.
i bought a 50 foot hose some years ago. cut it for the tractor use, and an extension that can reach the back tires on the trailer.
i normally pay speedco to air up the tires, as their machine have 150 psi. and a build in water separator.
i check my air Gage against the Speedco machine also.
i now ordered the new trailer with Supper single tires,
and a self inflated system.
i do not think it will work well !
i have very little trust that the air system can hold 125 Psi in the back of the trailer, some 60 foot behind the air pump.
more to come.
