TST 507 Tire Pressure Monitoring System, 2 Flow Thru Sensors for Metal Valve Stems by Truck System Technologies, TPMS for Caravans, Motorhomes and campervans

Worked great. Integrated well with my monitor

Adding these tire pressure caps to our tow vehicle gives me much more peace of mind. We drive a 45’ diesel pusher, being able to monitor the tire pressure and temperatures is added security. Have driven about 3,000 miles since installing, no issues so far.

Quality product.

Product was delivered on time and as advertised. It was easy to install, and does the job it is designed to do.

This is not a recommendation for this manufacturer. I have only had their monitor for a few months and it seems to work fine. It is a recommendation for the product. I have had tire pressure monitors for over 10 years and they have alerted me to serious tire problems several time which potentially averted major tire failures while driving. Blow outs can not only cause major accidents, but the shredded tires can cause thousands of dollars of damage to your coach, even if there is no accident. Ask any coach manufacturer what it costs to repair damage to compartments and side walls of coaches after a blow out.

Bought these to add to a vehicle Im now towing behind my RV. They work as expected. However, be aware that they are longer and in my case stick out beyond the tire sidewall. Also, they use a different battery than the non-flowthru sensors. The battery is a smaller 1632 and I suspect will not last as long the 2032 installed in the non-flowthru sensor.

Tough to program although TST has detailed video on YouTube.

I like these better than the banded interior tire models that break.

Mounted on tow car behind motorhome. Works as described

Works perfect
