What Tire Monitoring System to get?

Whatever you choose, get a system where the sensors have user-replaceable batteries. My system is not, and it's a pain to have to send the sensors back and purchase a replacement, discounted or not.

TST, 40 ft coach and toad pressures read without a repeater. Just changed out one of the batteries, took 10 minutes because I have the outer covering.

TST. I still want to hack the frequency and make a more real time monitor though. I am not a real fan of the cycling through the tires even though I know it's keeping an eye on the tires at all times.

433.2 MHz if you want to try yourself.

The TST system instantly displays the affected wheel when an alarm trips. That works well enough for me. I'd rather keep my eyes on the road than on the TPMS... ;)

I've had the TST system with flow-through stems now for two years. I have had more issues with them than I care to think.
Several of the stems worked intermittently and were sent back under warranty. The flow through stems are very hard to fill. Can take a long time. Installation can be tricky. You have to screw the stems on "just until the air stops leaking out the threads". If you over tighten then, they won't work.
Another issue that disturbs me more than anything was me hitting a curb and knocking off the complete valve stem. Everything broke off and fell to the ground. Not knowing that I had hit the curb, I kept driving. The monitor never went off! I noticed a handling issue and pulled to the side of the road and discovered a flat tire. The monitor never indicated a loss of pressure to the tire. TST's answer to this was that it only reads an active monitor. A lost sensor won't tell the monitor that it is gone.
Their sensors also do not play well with valve stem extenders. You may need to replace your extenders with valve stems that will allow proper fitment.

Just check pressures from time to time...replace tires after 5 years. TPM is pretty worthless and just another distraction. jmo after 9 years.

Over the past 8 years, our TST system has alerted us to sticking brake calipers on both our toad and motorhome, a failed wheel bearing on our toad, and a couple of tire air leaks on both the toad and motorhome. Any of those events could have been much more costly if not caught quickly. There's valid safety reasons why all cars and trucks under 10,000 lbs built in the past 10 years have been required by the NHTSA to have a TPMS installed. There's nothing distracting about a TPMS until it alerts on a potentially dangerous condition. And that's when you want it to attract your attention...

Never mind.
