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

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.

Do not buy the color screen addition of this system as the tire pressure read out us in dark blue and almost impossible to see in daylight driving.

Did just like product said driving down the road noticed the pressure was dropping off slowly told off look for a nail nothing. Folding the truck stop filled up air entire took off down the road again. About three miles down the road the system let me know the air was leaking out faster than normal and alerted me before it got too low on pressure turned around put on the spare should have done that the first time

had a different brand for years. This one out does it by a land fall. not at all sorry went to theTST

Same price as everywhere else. Work great. New design.

Work fine.

Works goood so far

Centrifugal force would render these road debris in 100 miles or less. Sorry, I cannot endorse these.

Tow Vehicle
