This way you can check the accuracy of your TPMS because both rear tires of each pair should show the identical pressure on you TPMS monitor.
Correction: I just looked into my documentation and found that I got the 80psi Cross Fire. The monitor shows the black indicator (good pressure) at 80 psi, and different color ID's with over and under pressure.
