However, the Firestone, Ford, and tire industry standards group handled the situation in a less than great way: they arbitrarily said that NO tire of that same size, on ANY vehicles, should br run below 26 psi, IN CASE the driver is too dumb to increase the psi ONLY when caryying a heavy load. So, vehicles that should actually be running 20 or 22 psi end up being run at 26 psi, which hurts ride, handling, tread life, traction, and safety ALL the time.
Given the apparently too-harsh ride that the HD trikes have due to cheap OEM shock absorbers, improper sag, and HD's fear of reproducing the Explorer problem when a trike owner adds a passenger and LOTS of luggage, and maybe even sone trailer tongue weight, simply accepting the 26 psi might not be the best idea.
As for changing the psi "target" in the system, that probably requires editing the ECU software to change the target psi so that you don't get the low psi alert until the psi is lower than the OEM target psi. Such editing requires tuning software. And no, the HD Bluetooth tuner will NOT allow you to do that. You would need an aftermarket tuner with much broader capabilities, and even then there is no guarantee that the aftermarket tuner designers even know about this problem on trikes, or are motivated to take on solving it. Their focus is normally on just engine performance.
Unfortunately, "covering" the alert light with tape or a decal deprives you of a bit of time to try to get to a place of safety and/or repair when you get a puncture on the highway. Myself, I would want to have that warning followed by a bit of time to get somewhere safe and where the puncture can be hopefully repaired.
So, it might be that you have to make a choice: run the lower psi for a notably better ride and lose your psi alert AND an easy way to monitor tire psi, or keep the alert system fully funcitonal but tolerate a worse ride ALL the time. Some choice to have to make!
