I'm looking for a decent quality tyre gauge for the car.

[dobbslc]

National tyres filled all my new Surf tyres to 45ps, they should be 29psi !

 

[Keithmac]

I use one similar to this at home, tallies up with the digital guage on my Milwaukee M12 inflator.

Gauges usually state the accuracy, CL1.5 means 1.5% of the range. If its a 200psi gauge then it could be 3psi out at any point. Its better to have a lower range gauge for increased accuracy.

I dont see point in going around with a guage. Tyre pressures will likely need a top up so I go around with the 12v inflator. I found the Mazda OE one is quite good but I have been meaning to get one of the bigger types for quickness.

Judging by the tyre pressures when I’ve had tyres changed, tyre companies never check them. First thing I do when I get back is recheck them, generally all over the place. I’ve got a couple of cheap digital gauges, & they both read the same, so I’m assuming they are accurate.

I do the same and check the wheelnut torque as well as they are normally well over specs

I had some new tyres fitted to my motorbike, I did query the pressure when he put 42 psi in as I normally ran on 36 psi, he said that was the correct pressure for the tyre, it was like riding on ice, so as soon as I got home I dropped it to 36 psi, sorted.

Virtually all the pressure gauge things I've got disagree to varying degrees, it's more a ballpark figure tbh, then again the cars an old land rover so not necessarily an exact science!

I have acces to several different digital tyre pressure gauges, and they all seem to be in close agreement i.e. all read within 1 PSI at 30PSI. Of course, they could all be wrong, but they are from different manufacturers.

You could try:-

Demon Tweeks

good choice over a range of prices.

 

[bricol]

PCL pencil gauge for quick checks.
Or the gauge on my PCL inflator for accuracy when filling.

None of my cars have TPMS, just one more thing to go wrong or get ******** up when fitting tyres in my opinion.

If you buy a car made after I think 2014, you'll have them - required by law, and an MOT fail if they aren't there or don't work - assuming the MOT tester notices of course.

I have thought about simply bolting them into a welded up length of pressurised RHS - but some of them need movement, ie wheel rotation, to do whatever it is they need to do.

The ones on my Dodge are amusing - I set all tyres to the same, correct, pressure of 32 psi - the dash display tells me pressure at each corner - can vary around the car from 25psi to 45 psi.

I use exactly that one - it agrees with two other, older, gauges - so either they are all wrong . . .

But, as I was told after I asked, the torque wrench used after the windy gun, "clicked" at the right setting so it must be right . . .

I felt an explanation wasn't going to work . . .

I had that once, told them to use the torque wrench instead of 2 minutes of "ugga duggas" on the windy gun, they knew I was watching through the waiting room window so were careful to do the side I could see properly, the other side was back to plenty of windy gun action as I couldn't see them, but I'm not deaf

PCL pencil gauge have been found to be very accurate over a long period of time.
It’s still my go to
I have a digital one too but it takes so long.
Turn on wait for beep to say it’s ready
Hold on valve and wait for it to measure pressure
Then it switches off
Rinse and repeat if you are adjusting pressure

Pcl is hold on valve read pressure
Lift slightly to bleed air and push in centre, hold on valve to recheck.

You should always come down to desired pressure too
So over inflate slightly then bleed back to desired pressure.
More accurate and removes the inconsistency in most gauges.

Without some kind of standard/checking facility nobody really knows what they have. I suppose something could be knocked up using a good quality calibrated liquid filled gauge mounted on a small receiver ( gas bottle),with a pressure regulator fitted and a schreader valve pulled into the side of it.

I thought all you had to do was kick the tyre
I use a US gauge that was free with a subscription to a MG magazine many years ago after they tested several and found it accurate. It's only has PSI scale and it's frustrating that most modern cars have the tyre pressure in BAR

 

[Ross365]

I use an inflator which I bought from Europarts some years ago; good inflator but its digital readout shows a reading which is 2psi low.

I'm a big fan of the old Dunlop pencil style gauges as per post #8.

If it did do you think the OP would be asking this question?

I wonder sometimes just what is going on....
"Y'all" don't have TPMS systems in the vehicles ?

I work with an engineer that came from the "Big 3" and was a part of the whole TPMS fiasco....He says he never wants to see another TPMS as long as he lives.
I notice mine go up and down with temp, as they should, but the change when driving is a pretty dramatic swing.

Older cars don’t have them, plus some (VW for one) don’t give you an actual pressure reading, they only tell you if a tyre is deflating. Also how would you know the system is working ok, without having something to check against?

 

[Dessieb2022]

My PCL pencil gauge is still accurate after living in various pockets for over thirty years.
For workshop use, I bought a Michelin Dainu Wonder gauge, which is excellent.

I have to agree, we have 2 Michelin gauges in our tyre workshop, excellent clip on connector that doesn't make the valve leak air and accurate too.

 

[Erie Fred]

Has everyone gone that critical on tire pressure ?
You could get your gage calibrated by a standards lab every 6 months, traceable to NIST/UK or other international standards, but really ?
