<strong>Yahoo Message Number: 82263</strong>I have my Smartire set up on the 3 axle coach, but I have a single axle car trailer and the screen setup only allows for a 2 axle car or trailer. My solution was to put the 2 spare sensors in the trailers spare wheel so they were in sight of the system as well, The trailer wheels are all set at 60 psi, but I keep getting warnings of -11 psi...
