not on cycle, but most newer cars and my newer tundra truck as a digital readout on dash.   All winter I set to 38-39 psi cold.  Just 2 weeks ago riding 3 hours north in 80 degree temps the readout was 44/45 psi on all 4 tires.  Amazing that going from say 20 degrees cold out to 80 degrees and long ride heating up the tires jumps from say 38 to 44 psi that much difference due to heat buildup on long HOTTER day rides.    I did not like the bouncy jolty ride from front end in town driving slower at 44 psi, too much psi for sure.  mfg specs psi I think around 33 to 35 psi, but that is WAY too low of pressure for 18 inch truck tires.  If set that low even at 36 psi cold, going slow parking lot cornering screeches the tires since IMO too low of pressure.

I like keeping my Valk tires at 35-40 PSI. Keeping them down what Honda said tends to wear cups in them and reduce tire life. Going above 40 PSI gives a rough ride. Even 35-40 PSI will throw your Speedometer / odometer / tripmeter off.
