TPMS Reset?

[Flip]

37 PSI is just fuckin' harsh for me, every bump is super magnified. I know Jeeps ride rough sitting on springs and solid axles.
But running at 32, I've noticed more even wear on my tires, and bumps are just generally softer. At 37 over time, I started to see a regular/noticeable difference in treadwear at the center of the tread.

No chalk test, just my eyes and back and what feels nice.

I run 33 psi because I had read that running a slightly lower psi with MT tires provides a little better traction with sudden stopping on slick or wet pavement. I don't know if there is any truth to this.

It’s probably true.
MTs are pretty knobby so there isn’t a ton of ground contact. A little lower pressure is going to provide much more of a contact patch.

The "right" air pressure depends on lots of things. One of the most significant is weight.

Doing a chalk test is probably the easiest way to figure it out. In a previous life I'd measure tread temperatures across the face of each tire after a run, but that might be considered overkill here.

Yep, and they're making money from us by selling us products like the Tazer.

Resistance is futile.

I understand but a mechanical fix maybe a tpms that’s programmed to send a programmed psi signal to fool the computer. Just saying. ?

Something that would have to compete with JScan, Tazer, etc. while doing orders of magnitude les And it completely removes the ability to automatically detect a leak? Would it need FCC approval since it'd have to broadcast a signal stronger than those coming from the tires?

That'd be a tough business case to justify.

Plus the different tire factor. My Toyo AT3’s have a “Max 35 psi” a quickie water test indicates ~30-32 psi. I run 34 to avoid cold morning warnings, inflate to 37 then drop to 32, repeat often. IMO the warning should cease above the 28 psi warning point making it much simpler.

Coil springs, since 1997 TJ's. Before that they were leaf springs, and they were harsh riding, compared to what we have now.
