After traveling full-time pulling a 5th wheel for 6 months and having several tire problems, I decided it was time to get a TPMS (Tire Pressure Monitoring System). If you don’t know what a TPMS is or are unsure if you need one for your RV, check out this article about RV TPMS systems.
After reading about several different systems, we decided to go with the EezTire T515 TPMS from EEZ RV Products.
We chose this system because it has great reviews on Amazon, has the largest LCD display, and has the best warranty (3 years). All the systems we looked at had similar features, but this one just seemed to stand out from the rest.

After using the EezTire TPMS for the last 6 months, I can say I am definitely satisfied with the product. It has worked flawlessly in allowing me to monitor the temperature and pressure of each tire on my 5th wheel RV.
The EezTire TPMS is comparable to any after-market RV TPMS out there. It has all the features one would expect in a decent tire pressure monitoring system. The main features I like about it include:
- Large LCD Display – No squinting to see the readings
- Both visual and audible alerts
- Replaceable sensor batteries
- Custom alarm for high temperature
- Custom alarm for low/high pressure
- Monitors up to 22 tires
- Easy setup
TPMS Initial SetupThis system comes with a great user manual. It is well written in plain English and has plenty of pictures and diagrams. I looked at the user manuals for several other TPMS systems and the EezTire manual is one of the best.
The step-by-step instructions were easy to follow for setting up the system. Initial setup included setting the desired high and low pressure alerts for each tire, setting the desired high temperature alert, and installing each sensor on the appropriate tire.
Each sensor screws right onto the end of the tire valve stem. There is an anti-theft device on each sensor, which is basically a waterproof housing that makes unscrewing the sensor difficult (unless you know how to do it). Once you learn how, unscrewing the sensors is easy for adding air when needed.
The monitor has a nice large 3.5 inch LCD display and comes with a suction cup mount and a 12-volt cigarette lighter adapter. It was easy to install above the dashboard in our truck by attaching the suction cup to the windshield.
Using the EezTire TPMS
It takes 5-10 minutes after turning on the monitor before all the sensors start displaying information. This is normal for all brands of TPMS I’ve looked at. I typically plug in the monitor as I’m getting the 5th wheel ready to hook up. By the time I have it hitched up and ready to roll, the monitor is displaying temperature and pressure information for all my tires.
The display continuously cycles through all the tires showing current temperature and pressure for each one. I’ve verified the fast leakage / blowout alarm several times by unscrewing a sensor from the valve stem of a tire. Sure enough, as soon as I pull it off the tire the monitor starts beeping and alerting me to a rapid loss of air pressure.
As the monitor cycles through each sensor, I can easily keep an eye on all my tires to make sure one isn’t getting hotter than the others. The monitor will alert me if the tire pressure goes above or below the thresholds I set. The user manual recommends setting the high pressure alarm at 20% above the recommended pressure and the low pressure alarm at 10% below. This accounts for the normal pressure fluctuation that occurs with changes in ambient temperature, tire temperature, and elevation.
For my tires, which I run at 80 PSI cold, I set the low pressure alarm at 72 PSI and the high pressure alarm at 96 PSI. The user manual explains how to do this.
I took this video to show a brief overview of the system in operation:
I definitely give the EezTire TPMS a 5-star rating. It’s worked as designed and puts my mind at ease whenever I’m dragging my big 5th wheel around.
