central tire inflation system on CUCV ?

[Dr. Lee]

I have come across a mention that the Pickups and Blazers sold to the military as early as 1984 had a central tire inflation system (CTIS) available. I found the on-line version of the Army's shop manual (at www.motormayhem.com) for the CUCV but it had no mention of the CTIS.

Any information anyone could provide, even anecdotal would be useful.

Thanx in advance, Dr. Lee

Seems Dana is the one that supplies the CTIS for the military. below is an explanation on how it works.

In the USMC circa 1992, we never had CTIS on anything except the Hummers.
CUCV was basically a civilian vehicle built to a military spec for ADMIN and BASIC transportation uses. It was never intended for a combat role. It was more of a cost saving venture than anything else. IRC, a CUCV was about 1/3 the cost of a Hummer. These CUCV would be square body chevy pickups and blazers from 1983-1987. There was a VERY limited number of "CUCV II" built on the GM400 platform but I never saw one in the USMC. Possible that the CUCVII's had a CTIS but I dont know.
The Main purpose of the CTIS in the military was to air down/up tires as needed for traction and environmental issues. The USMC implemented this on new hummers put into service around 1992(???) If your tire was shot it was not going to get aired up again by the CTIS. That was why we had run flat tires/rims. The run flat rim was an important part of the CTIS system. CTIS could be used to keep tires at a constant and help with slow leaks. Our bigger trucks, 2.5 and 5 ton, had on board air systems designed for external air use such as brakes, tools and inflation.

My father was a contracting officer's representative for the DLA and in conversations with him, it is possible that CTIS was an “option” in the CUCV contract, but not one that was ever actually produced - or produced in extremely low numbers.

Most often, things got eliminated due to budgets. They tried to shave off any options they could to get a cost down to a certain number and someone decided a particular option wasn’t necessary.
