To easily monitor up to 20 tires at the same time, consider incorporating extra Tire Linc TPMS sensors into your Tire Linc setup, which makes towing easy and straightforward when towing 5th wheel trailers, utility trailers, boats, and agricultural trailers. Installation is straightforward -- simply remove the valve stem cover of your tire and screw on the Tire Linc tire sensor. The sensor will read tire pressure and connect to your Tire Linc system, allowing you to keep a close watch on tire pressure from your smartphone while towing.
