Do you sell a tire pressure monitor system for a single axle trailer? I built a overland trailer with a single axle and a spare tire,so I have a total of 3 tires Id like to monitor. Thank you

It's great to hear from you again, Kenneth!
Yes, what you're wanting is the TST TPMS for Trailers and Cars - 2 Cap Sensors # TST63FR, and then you can add one more cap sensor with the part # TST47FR.
There aren't any TPMS that come with 3 sensors because most people just put the sensors on the active tires. I like your idea of putting one on the spare though!
Let me know if you have any other questions!

Hey Kenneth, how did the TST TPMS setup work out for your single axle trailer? I'm curious if adding that third sensor for the spare gave you the coverage you wanted. Your update could make it easier for the next person with a similar trailer build.
