I appreciate Tire Minder and their customer and product support. In less than a year of installing their product, he saved my truck and trailer from what was undoubtedly catastrophic damage on two separate occasions. For the first time in weeks since installing the Tire Minder, the device warned me when I returned from camping that a trailer tire was losing pressure. On the freeway, I could stop as soon as the tire deflated. If I hadn't been warned, this tire would have caused hundreds of dollars in damage. The second time was during a recent trip from Virginia to Texas. We arrived at a campground near Dallas and were in town the next day for some sightseeing. During a lunch break, I received a warning that the truck's right rear wheel was just a little short of air. When I managed to locate the pneumatic machine, I found that the valve stem was cracked and leaking. If I hadn't been warned, a leak might have occurred while towing a trailer.... I hate thinking about options. I've pulled followers my entire adult life and I'm fortunate that I haven't had any major setbacks. But since installing Tire Minder less than a year ago, it has saved me twice. Thanks for a great productβ¦. Rest assured, they save lives in the towing world.
