Product Description

Accutire's remote tire pressure monitor system helps you keep an eye on your vehicle tires so you do not lose air over a period of time. It is a fact: tires can lose 1 to 3 PSI per month. This is because molecules of air, under pressure, weave their way from the inside of the tire, through the rubber, to the outside. A drop in tire pressure could cause the tire to become overloaded, leading to excessive heat build-up. If a trailer tire is under-inflated, even for a short period of time, the tire could suffer internal damage. This system offers the right tool to keep tabs on the tire pressure of your auto, truck or trailer. The individual caps are programmable to read the tire pressure and alerts with an audible signal if a tire has a fast leak. The digital display is easy to read.

This review is from: Accutire MS-4378GB Remote Tire Pressure Monitor System for Auto and Trailer (Automotive)

First unit would not pick up signals from valve units. After receiving second unit
I determined that that the intructions were incorrect as to the setting for detecting the senders. (They say auto, I say manual) Even at that the system would detect 3 out of 4 senders ( senders were within inches of the receiver)
for about 10 minutes then go into the power on mode check never to work again. I spent many hours trying to give it a chance.

3.0 out of 5 stars Bigger and not to portable as expected!, May 13, 2010

The photos give a different impression about its real size, its bigger than expected, bigger than a regular mouse, also the valve cap are so big that you need to use wheel balance weight chip thanks to that this TPMS is not portable as expected.

I was expecting to use it on trips but not daily cause the caps look big and can be easily stolen.

In order to use it as I want (portable), i will look for others wheels balance weight chips that can be portable and have some spares.

Look for my share picture.

Hope this review can help.

1.0 out of 5 stars Garbage - do NOT buy this unit, December 21, 2010

This review is from: Accutire MS-4378GB Remote Tire Pressure Monitor System for Auto and Trailer (Automotive)

Ordered this a couple of days ago and it showed up last night. I was excited - seemed like everything I needed to retrofit a TPM system onto my older car. I'm bad about remembering to check the tire pressures, so for $80, I figured it'd be a good deal. Boy was I wrong.

First the good: the unit display is pretty well made, and the kit instructions are actually pretty decent. They also conveniently include a set of lead stick-on weights to balance the transmitters. The transmitters are pretty big; they replace the caps on the Schrader valves on your car. Each is about the size of an iPhone "cube" charger - the kind the comes with your iPhone... Huge, but not really that bad.

Now the bad: I followed the setup instructions explicitly; note that the units are NOT sync'd out of the box, and you do have to run through the "pairing" procedure. It's really easy, since you have to open each transmitter to remove the battery insulation tab that keeps them "shut off" while the unit is waiting for you on the store shelf. All programming entails is putting the unit in program mode (hold up & down for a few seconds until a tire blinks), select the right tire with up or down, and then install the battery into the matching tire cap. When you get all four paired, you hold up & down together, and the unit goes into "working" mode.

The problem? The unit refused to read the sensors. All four would pair successfully. Once installed on the car, there'd always be one (and it varied!) that would lose sync with the receiver. I couldn't actually get all four tires to work at the same time. Three out of four was the best I could do...and I have a small car - a VW Beetle!

After an hour of pairing and re-pairing the transmitters and receivers, without managing to get it to sync up to all four transmitters simultaneously, I gave up and returned the unit to Amazon.

Do yourself a favor and buy a better quality unit and stay away from this cheap piece of junk.
