Easiest to Install/Use Tire Pressure Monitoring System for Trailer Application

Question:

Hello, I am really confused about all of the TPMS Tire Minder information out there. We are getting new Sailun 14 ply tires installed to replace westlake 235/80/16 that say 110 psi but also say G load range which I cannot find anything online referring to this tire being 14 ply or a G load rating with 110 psi. My husband swears it is fine to run 80psi in these westlake tires, thankfully we have only traveled about 3000, miles so far, with that psi, then staying parked for 5 months at a time, now getting ready to travel for our first long haul this winter. I have researched until i am blue in the face, trying to find all of the safety factors, about to low or to high psi. I am grateful to ETrailer for all of your great information, so that I can now know what the dangers of low/high psi can do. So the new tires will have the metal stems, we tow with a shortbed Ram 3500 dually diesel if that helps. Please let us know the best TPMS system for beginners. I will probably be installing these myself since my husband doesn’t take psi seriously, so as a senior woman i need all of the guidance and help I can get. I will be learning how to check the air pressure myself also. TIA

The tire pressure monitoring system I would recommend for a "beginner" or anyone looking for the easiest to setup and easiest to use in general is the TST TPMS part # TST-507-FT-4. The reason I recommend it is because it installs easier by attaching to the valve stems (others mount in the tire), it's a flow through design which means you can inflate/deflate the tires without removing the sensors, and because it has a grayscale display instead of color which helps with the cost.

If you liked the idea of a color screen you'd want the # TST-507-FT-4-C instead.

You mentioned tire pressure which I wanted to mention also that with trailer tires you have to run the max pressure listed on the sidewall of the tire at all times. So what you do is inflate the tires (when cold) to the max rating PSI and you'll have the full tire weight capacity as well as minimize chance failure due to overheating.
