why is the 'kneeling' valve only for the spare? so says parts info. what does it do? mine has air leak in any position and I don't understand what it is meant to do.

CTIS
CTIS was first used in production on the American DUKW amphibious truck, which was introduced in 1942. The Czech Tatra T813's central inflation and deflation system was designed to maintain pressure even after multiple bullet punctures. Military-spec Tatra trucks are equipped with CTIS as standard. Several trucks used by the U.S. military, such as the HMMWV, HEMTT, and FMTV, are equipped with CTIS. The feature is also common in Soviet and Russian military trucks.
