You know what my AIRBUS got? Only brake temperatur indication! And this may be legaly inop.
Same on my B717. However the MEL condition is that the aircraft turnaround with brake temp inop is 50 minute turnarounds -- a significant disincentive for our operator!
Interestingly, the US ALPA is in agreeance with you. Their tech team commented on the 717's lack of TPMS when they flew a Boeing demonstrator at the type's introduction.
"
Because of the short-range/high-cycle type of flying that this aircraft will perform, Boeing preferred steel brakes--they cost less than carbon brakes, which are lighter and are preferred for longer-range aircraft that make comparatively fewer landings. Brake temperatures are displayed, but tire pressure is not, even as an option. Full-time tire pressure monitoring, although an option often removed (not by pilots), can be very effective in preventing a high-speed abort for a tire failure because of low tire pressure--a fully preventable event, if only the flight crew is given the proper information."
