Low tire pressure warning system. Whats up with that? No spare tire and no warning system? My 2004 Monterey Minivan even has it and it has a spare. I should think a LTPWS would be a must on a truck without a spare. The earlier you fix that tire the better off your chances of the inflater goo working. I look at something like that as a safety issue, I just figured it was there until I looked in the book. How hard would it have been to put the C5 tire pressure system on the SSR I ask? Not hard at all I would think, 4 sensors a dash reciever and a little DIC programming.
