TPMS pressure and temp settings

[D Sgt]

Hello all and thanks for reading! I just got a new TPMS system for my Shasta Phoenix 5er. It's a new unit and we've put maybe 1500 miles on since picking it up new from the dealer in Ca. It came with Ly 188 Constancy ST235/80R16 E with a max inflation of 80 PSI. I have TST 507 sensors and would like guidance on min/pressure and temp settings. I live in Las Vegas and the temp goes up pretty high in the summer. Suggestions? Thanks for any suggestions. Will probably replace the tires next summer/spring but for now...

What should I set my pressure and temperature parameters at in the display? The recommended high-pressure alarm should be set at 20% above your normal tire pressure you typically run in your tires. The low-pressure alarm should be set at 10% below your normal tire pressure. In areas of high ambient heat, like Arizona or Florida, the high-pressure alarm should be set to 25% above your normal operating pressure to avoid unnecessary alerts. For your temperature setting, the default of 158° is safe for all tires. Tires typically fail between 170 –200° F.

Yes, your user's manual will give sufficient instructions.

I’m in Vegas also with the same set up. I think the 507 lowest setting is 145 so I started there. As for pressure I went right at 20%.

So this is old search, but my tires on my 2014 Rockwood Signature which I purchased used last November has Trail Express tires on them. I expressed concern on their age at the time of purchase but was assured they were in good shape.
So I have been out 3 times camping within 1hour drive of home each. Now I see cracks around tire by rims. I put spare on before leaving last campground. I am wondering if I should replace all now even though not looking like this one. OR get more use out of the others. From the thread in comments they are CRAPPY tires?]

You must be more of a gambler than me. I'd have all 5 in a dumpster.

D Sgt, see if this post helps:

Linda Hartin, ST tires age out at 4-5 years. Your 2014 was likely built in 2013. Check the date code on them and make a decision but my guess is you're on borrowed time at this point. See this site (not mine) for how to read it:

I would replace those tires immediately with Goodyear Endurance tires. They are a ticking time bomb.
