Internal tire sensor monitors your tire pressure and temperature and sends real-time info to your TST wireless monitor. It provides more accurate temperature measurements when compared with valve-stem-mounted tire sensors.

Specs:
Note: Dual wheel equipped vehicles MUST be mounted with valve stems oriented 180 from each other to allow pairing of internal TPMS Sensors.
These sensor seems to be very accurate. I use the TST system when adding air to my tires so they become all the same amount and makes it easy to watch pressure changes. When I rotate the tires it takes me about 10 min to reprogram them all in their new location. I do wish there was a way to replace the battery in the sensor but I am on my 1st year of use without issues and strong signals. Discount tire installed them for me at no charge when I bought new tires from them. That was nice.
I bought 8 of the TST Internal Tire Sensors for my 507 display.
We were able to sync all 8 sensors prior to installation on the vehicle.
The sensors will be installed on the vehicle later this year.
There was a delay in shipping the units because eTrailer needed to get the units from the manufacture. eTrailer kept me informed of the order status in a timely manner. I did not mind the delay because it ensured that all 8 units were factory fresh.
I would definitely order from eTrailer again.
Everything has arrived fine, packaging was good. The USPS indicated yesterday that the parts would arrive tomorrow, two days later than originally thought but it arrived today. That is probably not the fault of ETrailer. I was able to schedule the tire installation with the TPMS sensors for early next week.
Exact fit replacement. My display unit recognized the new tire sensor during the learn process immediately. Customer service was excellent at ETrailer. Had an issue with delayed shipment but that was on the USPS and not E-Trailer.
E-Trailer was great and sent out a replacement sensor UPS 3 day. The replacement sent UPS was due to arrive tomorrow 3/19/24 and low and behold USPS showed up today 16 days after shipment. Just have to take the rim & tire to be mounted tomorrow.
As usual great service from this company. In stock and shipped the same day and had them 2 days early. Always great customer service, Thank you all.
Replaced one sensor that was damaged from a blowout. Sensor indicated increased temperature above normal that allowed me to pull over and slowdown just before tire blew, which prevented damage to m camper. New sensor was easy for tire shop to install and programming was simple.
Can't comment on the sensors yet. Have to wait for installation of new tires in August to install the sensors. Will comment then.
I received on time as told at the time of the order. My sales representative was very professional. I bought this as a replacement for one that was found broken at the time that I bought new tires. I reprogrammed the new sensor before I installed it on the tire and worked perfectly. I do think the individual sensor cost is a little high.
Thanks etrailer
Just what I needed !! Easier to get them from Etrailer’s website than TST truck !! Price was right too !!
These are somewhat fragile when replacing the tire on your trailer. The tire shop needs to know where the sensor is oriented so their bead breakdown machine doesn’t destroy it when taking the tire off the rim. I replaced mine because the strap broke inside and the parts were flopping around inside the tire.

I have one of the sensors that isn’t working. I haven’t taken the tire in to repair it since the other three sensors are on and the tire is not leaking. I’m not sure why it isn’t transmitting but I’ve tried to program it multiple times wi th out success.
Works as advertised
Great product at excellent price. Delivery was quick.
Works great. Good quality sensor. Bought this for our second spare tire for our Alaska trip. Integrated easily with our existing TST-507. Recommended.
Great responsive service, exactly the right part to get us back on the road safely.
Delivered ahead of schedule.
It’s rare these days to have such excellent quality, and especially SERVICE!!
Delivery was two days ahead of schedule, and communication was excellent.
All is proper except 1 thing... 1) there isn't any indication (ie. label/marking) of the 'birthdate' of the internal batteries. Even though these are "new" from etrailer, these might have sat on the shelf for many months be me buying them. I have no idea. Thus, a label/marking of Date would help more. Thx.
Excellent speed of delivery of order
I was a little upset when the package tracking number said estimated delivery date was Sat, but it did not arrive until today, Tues 20 Aug 2024. I realize this is an estimated date, and you have no control over shipping but thank you for getting the item out. Thanks
Installed and working fine.
Never have to worry about it getting damaged or stollen. Simple to setup. Easy to install if you are getting new tires anyway.
Easy to find on website. Product arrived a day before scheduled. Product was as advertised.
We ordered the TST tire sensors and received them a few days later. They were packed well and arrived in perfect shape. We would order again from e-trailer. Thank you for great service.
Outstanding! Hoorah!
We traded our trailer with these and the new camper did not have them preinstalled. The peace of mind and safety this system provides is beyond explanation. Leave home or camp with all tires at the same pressure. Adjust pressures in changing weather. Monitor tire temps that prepare of impending tire failure. What sealed the deal for us was having a very hot tire. It turned out to be a dangerous condition, bent axle. Thankfully it was covered by warranty. TST is the American Express of camping, we don't leave home without it (I also added valve stem monitors for truck & tow spares). Highly recommend!

My tire sensor still works flawlessly. Definitely would recommend this product & E-Trailer.
