Essential Info

The government estimates that 25% to 33% of all the vehicles on the road have at least one tire that is dangerously underinflated. Being only 6 psi below the recommended pressure can cause a catastrophic blowout or loss of control. Even if you avoid a blowout, low pressure causes premature tire wear of up to 25% reduction in tire life, and consumes 5% more gas. And overinflation is nearly as bad, as it reduces the contact patch with the road, negatively affecting handling and braking. What's the solution, other than driving yourself crazy checking your tire pressures every day? Install this Tire Pressure Monitoring System (TPMS) and your car's tire pressures are monitored all the time you are driving, and you will be alerted instantly if one (or more) tire loses pressure or if temperatures approach dangerous levels. Installation is super easy: charge the display, set the vehicle maker's recommended pressures, then replace each tire's valve caps one at a time as you program the display. That's it! You can't look at a tire and tell if it is inflated properly, but now you can look at your dashboard and know you're safe.

Add more Minder Research Transmitters to up to a total of 22 tires. If your car or truck has aluminum valve stems, use TireMinder Transmitters for Aluminum Valves.

    Pressure reads within .4 psi at 80. You need to have an accurate gauge. I checked my old spring type gauge with two tire shops and found it off 6 psi. I got a digital gauge and it was on with the same two shops. Most digital gauges are +- 1. very pleased with the tire minder.

    I received the Tire Minder System a few weeks ago and it works great. We pull a travel trailer and it is a comfort to know the status of the tires at all times. I called their tech support once with a question and they were very courteous and answered the question instantly without going through some script...I would recommend this product highly and Smarthome shipped the system ontime and as advertised.

    Haven't installed as yet. Probably won't until October.
    DAVID -- houston, TX   7/25/2013
    Installation (5 stars) Ease of use (5 stars) Overall value (3 stars) because of the way it operates. To see the temperature & pressure of any tire you must scroll through all the tires with a button. The button comes with an annoyingly loud "beep". There is no way to decrease the volume or silence that beep. Otherwise it works great.
    THOMAS -- billings, MT   6/10/2013
    The jury is still out. I used it on a 1,200 mile trip right after I first received it. It worked well for the first 800 miles then two of the four sensors started giving me false low pressure warnings and/or indicating that I had a psi 100+ higher that it really was. I called the manufacturer when I got home and they said send it back to them (on my dime). That was two weeks ago and I haven't heard back from them. On the phone they told me that it would be a two or three day turnaround. They installed easily and the wireless function worked well (even with the GPS) so if the manufacture fixes them I should be happy with them.
    LINDA -- cheyenne, WY   7/19/2012
    This item is completely garbage. It did not tell us when tire pressure was low. We only got a "no signal" notice on three out of the four tires and then a tire on our travel trailer blew completely, almost also shreading the tire behind it. We purchased this item to prevent this kind of event and it did absolutely nothing. Don't waste your money and I hope to get our money back.
    JOAN -- lancaster, CA   3/30/2012
    This was a gift to my husband. He has been very busy and has not istalled at yet, but seems very pleased with the tire monitoring system
