What ever gauge you buy get one where your main tyre pressure comes right in the middle if it's scale because that is where they are calibrated, A 150psi Gauge might look impressive but if you normal pressures are around 30 psi then there is a big chance it won't be accurate because a 150psi gauge has a 2 to 3% accuracy limit and at 150 psi can be off by as much as 4.5 psi and still pass the calibration tests whats more a 150psi gauge is only within calibration limits between 37.5 and 112.5psi
After all those tests I did and buying cheap gauges to the most expensive one money can buy I would say if your pressures are around 20 to 40 psi I would go with the ARB Low Pressure Gauge because they are well under the limits, But Don't bother with digital Gauges because the chance of finding 2 that read the same is nigh on impossible the major factor with digital gages is that they are only as good as the pressure sensors they buy to put in them, under 100 bucks and it will have a cheap sensor, When it comes to buying a digital gauges the higher the cost the better the sensors,
The ARB Low Pressure Gauge matched the 400 dollar gauge pound for pound and you can get the ARB LP Gauges for about 20 to 30 bucks,
Hope that helps.

They are ok but the soon loose their accuracy due to wear and dust and dirt, they were ok back before we had fancy tyres with fancy compounds, But modern cars need something a bit more high tech because of the speed and handling and weights of modern cars,
There is a couple of good reasons to buy a good quality Tyre Gauge, No 1 being safety for you and your family along with other road users, 2) to maximize the benefits of buying good tyres in the first place, 3) Having the correct Tyre Pressures improves handling and ride conditions as well as fuel economy, 4) One major issue that people do not realize and that is if you are in a Accident and the Insurers check your Tyre Pressures and they are incorrect they have been known to Void a persons Insurance Claim. Which can lead to being charged with fraud along with being Sued by 3rd party persons or companies.

You're right, but the 50 year old small shiny one is carried in it's original container i.e. no dust or dirt and it is still accurate. Been around tyres for for 60 odd years, never, ever take a risk with tyres, steering and brakes (and a few other things). One thing that annoys me and probably a lot of others is the poor accuracy of the readings you often get at a service station.

I think you guys are over thinking it a bit tyre pressures being out 2-3 psi wont make the slightest difference and if you are relying on tyre pressures being right on a certain pressure to make towing or driving safe you need to look at the weight of your vehicle or how you are loading it.
I have gauges like the above ones had them since I did my trade and that was 30 years ago and they work fine

On a recent study only 3 in every 20 Servo's have their gauges checked and the same regarding how well their compressors perform.
A tyre gauges accuracy has to be within 2% of it's scale from the 25% mark to the 75% mark and within 3% below the 25% mark and above it's 75% mark, If a gauge is out but it is within the figures below then it is accurate as far as trading standards are concerned,
Out of 14 gauges from $5.00 gauges from Ebay to gauges costing over $350.00 from specialty Racing Companies only one gause was 0.8 PSI out. The results can be found Here.

Here are the tolerances of gauges that use a fully geared, solid brass precision movement with bronze bourdon tube, .
The mechanical accuracy rating is 2% from 25% to 75% of scale and 3% below 25% and above 75%.
A 15 psi tire gauge is accurate to 0.5 psi from 4 psi to 11 psi and is calibrated to 0.25 psi at 7.5 psi.
A 30 psi tire gauge is accurate to 0.6 psi from 8 psi to 22 psi and is calibrated to 0.5 psi at 15 psi.
A 60 psi tire gauge is accurate to +/- 1.2 psi from 15 to 45 psi and is calibrated to 1 psi at 30 psi.
A 100 psi tire gauge is accurate to 2 psi from 25 to 75 psi and is calibrated to 1.5 psi at 50 psi.
A 160 psi tire gauge is accurate to 3.2 psi from 40 - 120 and is calibrated to 2 psi at 80 psi.

All the facts and figures I have worked with for years And All Additional Information was supplied By Longacre Racing Products and Moroso Racing Products and Michelin Tyres, and Goodyear Tyres along with a few other Racing companies, No rambling Just Facts.

When the 1997 Ford Explorer came out in the US they had hundreds of claims along with being Sued for man Slaughter, Ford put the Blame on FireStone Tyres, Firestone put the blame on ford, Thing was ford made the track of that model too Narrow than earlier models, The Ford designers came up with the Idea that if they reduced they Tyre pressures by 3 to 4 psi that would improve the vehicles grip, So that is what ford did Firestone insisted that the tyres had to have a certain PSI to cope with the weight and power of the vehicle but ford thought they new best, So it resulted it both companies blaming each other,
Hundreds of owners found that their ford explorers would just change lanes or blow tyres Rolling the vehicle at motorway speeds with people being thrown from the vehicles at speeds of up to 120kph.
The end results are still going through the courts and because of ford lowering the tyre pressures just by 3 to 4 psi has resulted in many Deaths and hundreds of people being crippled for life and many others now live with loss of family members or life changing injuries.
So the She'll be right attitude won't work here, Imagine for a minute a person loads their vehicle up with the weight of 5 or 7 people plus all their gear and does not adjust their tyre pressures from 28psi up to 36psi and then add to the fact that they are using an old hand me down tyre gauge that just happens to read 3 psi LOW add that to the 8psi they are already under inflated that's and 11 psi variation and just asking for trouble, The blame got put on to firestone but ford made the tyre pressures lower than firestone recommended.
Anyway here is the video about the US Government hearing and Ford vs Firestone, But there has been 100's if not 0000's of Claims over the deaths and injuries sustained because of this.

You are 100% Wrong, watch the video in my post above.
You can post as much as you like Blocker. Say what you want to say and vice versa. Some people here just like to argue.
