Optimal Tire PSI When Running
My ST 215/75R14 Maxxis M8008 tires are set to 50 psi cold in the morning. I know that tire pressure increases roughly 1 psi for every 10* increase in ambient air temp as the day heats up. I also kno...

If I remember correctly, the TST tpms installation literature recommends setting the high pressure alarm at 20% higher than the cold psi. That equates to 60 psi for my tires (I was expecting it to alarm when the one tire hit 60 psi but it didn't). The obvious implication is that TST considers a psi increase of greater than 20% over cold psi to be a safety issue.
If the consensus is that a higher psi range is acceptable, I will reprogram the TST system to alarm at a higher setting, say 30% over cold psi.

As stated, don't worry about the high pressure warning. Just set your alarm for low pressure warning and go on vacation. This from a guy that takes dozens and dozens of tire temp and pressures on the weekend. :)
