Settings for min/max tpms MBS 3500

Well pressure is never going to increase beyond what you put in it plus normal temp/elevation induced temporary increases.
And low pressure is up to you.
Assume the threshold is the same for all positions, set it whatever you want “below” your lowest cold inflation psi.
Also a good time, since you’re obviously keenly concerned about tire pressures, to very what you should be running and not just what the door sticker says on a modified chassis.
It’s probably closer to correct than some, but do you know if it is?

Example, if I ran “sticker pressures” on my truck all the time, I’d by now have needed a new kidneys, beat up some steering components unduly and worn tires out improperly.

This is a link that i was reading for info bc i bought a tpms. Im just learning. Appears it might be brand specific .

Thanks for all the responses. Yeah I hear you on running sticker PSI but I have to say the ones on the MBS are pretty good and it rides nice so I'm going to stick with those.

The ranges make sense are in line with what I've run on previous TMPS systems. Before I had TST and this one is a tire minder. Already I like the tire minder better for a few reasons but you actually don't have to set thresholds if you don't want. I can tell when a tire is losing too much pressure or gaining too much heat by keeping an eye on it so a threshold alert might not be something I set right now. It did give me an alarm yesterday when we came home from dinner and one tire is completely flat. Guessing I either don't have one tight enough or there is another issue but sorting that out today and glad it happened in the driveway and a week out from our next trip. I will say the MBS wheel covers are NOT TPMS friendly. The holes are small, difficult to line up and a total PITA getting back on. I may actually drill the holes out larger where the TPMS' are. There just isn't enough tolerance for my liking.

I have a TST, This is. what THEY say to do -

Note: Tire pressure data charts are available on your tire manufactures website.
The high tire pressure alarm should be set approximately 25% above that
setting. If you would like to set the cold tire pressure based on your load
weight, we recommend that you take your vehicle to a local weight station
professional for a more precise cold pressure recommendation that is
based off your load weight.

I run my tires at 115# , when I purchased the TST they did all the set up for me. The first question was what psi do I run at. They set my max pressure alarm at 143.

Is it right??? do they know better than I , I hope so! !

Not sure why there would ever need to be a “max” pressure alarm?
Bout as useless as teats on a boar…
If the tire could ever build enough heat to increase pressure that dramatically, it would be low to start with (causing) heat and never hit the alarm threshold.

Or maybe to warn you if you set the Max cold pressure in the Arctic at sea level in the winter then drove straight to South America and it was like 90degrees at 9000ft in the Northern Andes mtns in the dead of summer. That “might” trigger it! Lol
