I installed the Tymate 6 sensor system (also available on Amazon) a few months ago. In order to install the sensors on the dually wheels I also bought four short 1-1/4" tire stem extensions.
The Tymate sensors are not particularly accurate. After carefully pumping the fronts to 75 psi and the rears to 65 psi per Thor's sticker the Tymate showed the fronts as 71 and 77 and the rears as 63 to 70. It got worse as they heated up.
But a tire management system is to give a warning if one gets too low and I just set the low and high limit broad enough so I don't get spurious alarms.
The Tymate 6 sensor module has two screens that alternate, one for the four inner tires and another for the outside rear duallies. The solar charger works so well that i just leave it on the dash and forget about charging. It is always charged up even though the front points north so it gets little direct sun. Indirect is fine.
All in all, I like it.
