Are you sure? I just had a look at the manual for a 767 optioned with tyre pressure indications. The manuals don't show Maintainance Page tyre pressure displays and I don't see any room on the Maintenance pages for tyre pressure indications. All the data seems to be displayed on the Status page.
Irrespective, this aircraft didn't even have brake temp indications on EICAS.
So the crew had no obvious clue that anything was seriously amiss with the landing gear. People should be a bit less eager to blame them when there is a cockup such as this.
That said, it is not obvious what the proper fix would be. A wheels cam seems more cost than benefit if even a humble pressure sensor poses problems.
