Here is what I did. I purchased these steel T stems and the Fobo Bike 2 TPMS (Tire Pressure Monitoring System). The app installs on my phone which I mount on a Quad-Lock holder where the GPS used to be. You can see your tire pressures and temperatures in real-time. Did you realize that your tires can gain +/-10lbs of pressure when it's hot out? You can set warnings with alarms for min/max pressure alerts. The T stems allow you to add air/nitrogen without removing the TPMS. It is a very slick, convenient setup. I also run ceramic balance beads which work perfectly.
