    Hmm this or a TPM?

    What is the point of this product, why not just use one of the many free hose pumps, at servos or them bike maintenance stops?

      Because I can never get the hose to stretch long enough to reach my house.

        You need this to see if your tires are flat, why not just buy a pump?

      •  

        This is my view:

        If your tyre is flat then you wouldn't check its pressure rather you would pump it or replace it.

        If you visually noticed that tyre(s) lost some pressure but not flat then you would either go to nearest servo to top up or you would use your own pump (if you have)

        I drive my car all day to earn my bread. I visually check my tyres everyday before I start. If I notice any loss of pressure I go to a servo and pump it up.

        In my view this only become useful if you are in doubt about the situation, couldn't make the decision visually. It would save you some minor time (15 minutes max).

        Long story short: it is just $10 :)

        Sorry in advance if I couldn't think of any other possibility.

      Because they can be wildly inaccurate or faulty.
      I know of several occasions where they've left people with a flat tyre. Myself included.

        Sorry my point I am trying to make is that this item is not needed, you spend the extra 3.85$ + postage, and get a air pump that has a air gauge inbuilt.

        People say you need this because the pumps don't work at servos, inaccurate or plain don't work, how is this device going to save you, when in the end you are going to need a pump.

          Because this is a whole lot easier to just quickly check than getting out the whole pump and connecting that up.
          This you could check each tyre in less than a minute.
          Whereas getting out a pump and hooking it up is much more time consuming.

          You should be checking your tyre pressure weekly. But it's incredibly unlikely they'll need filling up that often. (If they do, there's something wrong with your tyres)

            @Rail Rider95: Yes, exactly.

            I have a compressor, but I like to check pressures more regularly than I need to pump them. I'd need to unwind the hose, drag it around the cars in the limited space of the garage which ends up getting caught under the tyres and me swearing so it's just more convenient to have a seperate pressure gauge.

            The biggest issue with these cheap gauges is not knowing how accurate they are or being able to calibrate them. I've got a couple that I've acquired over time, all different readouts. The one I use most now can be used standalone or inline with my compressor so is best of both worlds.

      I know right, what are people planning to do with this, measure the pressure with one device, the change over to the pump with the inbuilt pressure gauge?

        Those gauges are inaccurate

        I have something similar and use it to check tyre pressure to tell me if all 4 are equal and if i need to air-up at the servo - its a lot quicker to check one or all of the tyres frequently to make sure you get good economy than to use the air hose at the servo if you don't need to.

          Best comment ever, you're the only person to mention the fuel economy, not even the makes of the gimmick device, state the benefits of the fuel economy. Lol

          Have an upvote.

          In addition to being able to check the cold pressure. Which is the correct way to accurately measure the tyre pressure.
          And cold pressure is actually what the manufacturers list.

    Any different to this one, OP? Looks identical.
