Well my cheap pen gauge actually blew apart over the weekend, thankfully did not hit the car or injury me when it exploded. I needed a "real" gauge that is accurate and will not explode, any suggestions?

thanks!

As I recall, the last time I filled up I compared the car display to my tire gauge. Ignition on and TPMS. Wheels do not need to be rolling nor engine running. Display matched my fancy gauge almost exactly and in real time. Save your money.

The LongAcre Racing gauges are considered to be some of the best. They have a few choices. I have the liquid-filled 0-60 lb gauge and it works great. The liquid fill isn't really necessary for most uses but I was buying at a shop where I owed them a favor so I bought the better one just to be nice.

You can buy them at a variety of sources. They also have a digital if that is what you'd prefer.

I have used these for a few years and they have worked very well. I also have a pen gauge as a backup but never use them.

I use a Craftsman digital gauge. Its readings are super close to the TPMS. Cheaper through Amazon than the Sears link below.

Another vote for Longacre. I bought mine off Amazon

Liquid filled - they supposed to be more accurate than digital?

Absorbs vibration, lubricates and prevents corrosion in moving parts, and makes readings more stable.

My experience with digital gauges is they last a year or two, then it's time for a new one.

Edit: I misread the question so I'm striking the answer. I was comparing to a normal needle-based gauge.
Yes, The small additional step is that before using each day you open/close the valve on the top to equalize the gauge to current atmospheric pressure.

Just a thought in general: It is important to be sure to understand the difference between accuracy and resolution. A lot of gauges out there will claim high resolution, for example claiming that they give readings in 0.1 lb increments. They are not necessarily highly accurate though. Ideally you want a gauge with high accuracy, meaning that the reading is correct in an absolute sense.

The LongAcre gauges are some of the most accurate out there. Likely more accurate than needed for our cars in general use, but why not go for good accuracy when it is available. A good quality gauge will list both its accuracy and its resolution.

+1 for this craftsman. Has also integrated flashlight. Extremely accurate and functional!

Same here, highly recommend Longacre and it is much more accurate than the cheap digital one I had previously. I have this one and it is excellent.

The Longacre gauge is a great choice. If you don't want a digital gauge, I like this one.

I like the old-style mechanical gauge. It's an Auto Pro Racing brand. I've tested it against some of the best ones.

My driving style works well at about cold 34 #'s on the fronts and 37 #'s on the rear. My car came with Goodyears and I replaced them with four last November (the fronts were 1/2 worn). The pressures go to ~36 hot front and 39 rear. It works well for me, and your optimal pressure will probably be different.

The real gauge can be a pound or two off the Porsche Computer. Every tire is different as every driver is different. It is always a lot of testing with keeping notes.
