TireTech On Wireless Tire Pressure Monitoring System w/ Brass Transmitters 0-232 psi (4)

I just got through installing this on my 30 foot travel trailer. Instructions are straightforward and installation was easy.UPDATE: (one year later)I purchased the TireTech TP7001 Wireless Tire Pressure Monitoring System on Amazon a year ago. Last summer I had a blowout on the front axle and I believe that tire knocked the one off behind it, so two tires. At the time I came to the conclusion that I forgot to turn on the TMS and let it sync before we left the camp area. Because it went into alarm about 15 minutes AFTER the blowout when I hit the ON button to see why it didn't alarm.Working with company now to see if we can resolve the issue.I purchased two new tire monitors last month to replace the ones I lost before a long tip last weekend.This week on the way home I had another blowout and NO alarms on the TMS. (My complaint with the tires is another topic) I specifically took the time at camp to turn on the TMS and ensure all the tire monitors where in sync and the system was working as intended. I even scrolled through the tires as we traveled and watched the pressures and temps slowly increase. As I was changing the flat my wife walks up to tell me the TMS just went into alarm. I had already taken the tire monitor off and put it in the truck.I spent $200 for the system and $80 for two replacement tire monitors for a product failed to work as advertised, twice.

This unit does not do well on trailers. You have to be closer than 10 ft for the sensors to work and that is after you unscrew them and screw them back on to wake them up. I can drive 30 miles and walk back to the trailer, unscrew one and go back to truck to see if alarms, nothing, no alarm. That's waiting for 10 minutes just in case it is slow to communicate.I would not recommend use on trailer unless the have an extender.One thing it is easy to set up and program.(Company contacted me after review and offered a replacement. New unit received and it works way better than first unit. Having trouble with one pressure setting but haven't had time to work on it yet. I now do plan on ordering another unit to use on different trailer. If it doesn't work right contact company and they will make it right!)

Bought a four sensor system. It was fairly easy to install and calibrate. After several months of good service one sensor failed hard. I contacted the distributor and they directed me to send them the failed sensor. After receiving my sensor they sent me another one. I installed and calibrated the new sensor and departed on a 600 mile trip. 300 hundred miles into the trip the sensor they sent me alarmed showing low pressure. I manually checked the tire pressure and it measured good. On the remainder of the trip, the sensor bounced between 35 and 55 PSI. Obviously the sensor electronics failed. I'm undecided whether to cut my losses and dump the system or pay $56.00 for two more sensors.

After 8 months the digital monitor stopped working. I've reached out to the vendor to see about getting a replacement under warranty. No response. When it worked, it worked well. Installed on a 40' fifth wheel, alarm went off as tire blow out occurred allowing me to pull over immediately and avoid additional damage.

Works great!!! Used on a rural mail delivery vehicle, on rough country roads for over 100 miles every day, and has worked flawlessly. saves tires and pays for itself.

Have not been able to get the sensors to synch yet. After a week of trying. Believe the directions could be done much better. At this point I am close to returning them .

Used it for one trip with our trailer and it didn't work right from the beginning. It was hit and miss with the syncing of sensors, then the 12v charger for the base station fell apart. The end of the charger where it goes into the car outlet, broke and the fuse came out. Then the batteries capture plate on two of the wheel sensors became un-soldered from the base. It's now just past the 90 day return time and I am stuck with a broken unit that is not worth fixing. I usually like everything I buy on Amazon, and this is the first bad review that I written, and am still pretty pissed.

works great, didn't need the relay sensor for my 28 ft trailer. took all of the worry out of the trips I took. if you do the initial calibration correct, it is a great product.
