......knows the pressures of his tyres.
But a man with TWO pressure gauges is never quite sure.
Just bought a spangly new calibrated pressure guage, supposed to be accurate to within 0.5 psi. *smug*
At whatever reference temp...blah, blah... *even more smug*
So I now have four of the things...and the variance between lowest & highest readings on them (at 30 psi) is.....wait for it.... 7 psi's.
That's almost an arm full.
Come to the conclusion, you're better off just kicking the tyre when you need to check these things...
You need to get out more........but check your tyres before you do.
Do you know whether you bought a front or rear tyre gauge? That maybe the cause of the difference....I'd check with the retailer or manufacturer.
how long is it in cal for, I could give you a clue
Gauge, meh! All you need is a pick handle to whack each tyre, just like the Aussie road train drivers do!
So my butler and driver tell me. Scandalous, isn't it.

Why would they be calibrated differently? Same tyres front and back and pressure is pressure.
I know some cars have recommended lower pressure in rear tyres due to engine weight over the fronts, but … ?
Don’t forget that continental gauges are calibrated for left hand drive cars.
I thought it was due to the difference between French and UK air rather than drive side.
Was it a autoreifenhochdruckprüfgerät from Lidl?
Whoosshhhhh...
That's what I thought but wasn't sure whether it was said in jest or serious...

They only use Parisian air to inflate tyres at the most exclusive 'auto boutiques' of Kensington & Knightsbridge due to high import costs.
In Scunthorpe Kwikfit use tramps farts...saves firing the compressor up

This is true, they really raise the bar.
Da-Dum-Tish....I see what you did there..

You clearly need to put some summer air in your tyres.

I thought it was purely psichological?
The government has announced a massive tax hike on new tyre sales from May 2019.....something to do with inflation.

Is the low guage made by VW/Audi ?

I bought a new gauge. It doesn't match the one on my bike pump. I reasoned that the more recently calibrated one is more likely to be accurate.
You're comparing a new calibrated gauge to an old one calibrated many years ago?
Just out of interest, what’s the average reading?

If its a new gauge it might be calibrated for Helium as thats what the sports cars use. I definitely check if its a right hand or left hand first as thats caught me out before. Dont be too deflated with the new gauge, as stated above it could just be raising the bar.

I suspect that you're taking readings at different heights above sea level so always take your readings either at the top or bottom of the hill....

The small pneumatic pencil-style gauges are usually the most accurate. I use a foot pump for setting tyre pressures but the gauge fixed to it is way out, I don’t rely on it.
I just priced a new pressure gauge, they are quite pricey. Must be inflation . . .
F.T.F.A.
I was told that pencil gauges made by PCL are the best.
This thread has really cheered me up by the way, although I’m starting to think some of you guys may have a rather overinflated opinion of your comedic talents.
The three best lines of British comedy:
1) “that’s very nearly an arm full”
2) “you started it”
3) “he’ll not sell many ice creams going at that speed”
Gauges are such a hassle...and dirty, too! I usually rely on the visual method: comparing the amount of side flex of the front and rear tires on one side versus the other side. I view the tires from almost directly in front of the side or directly behind the side, kind of like the views seen below. You can't just look at the tire directly face on, as its flex will not be noticeable. Combined with my car's low tire pressure warning system, this visual technique is quite effective on a daily/weekly basis. Another tip: Check your tire pressure when the tires are cold, and compare to the recommended PSI. When you arrive at the air pump, ADD the number of pounds each tire was deficient, since your tires would now read artificially higher due to the warmer inside air temperatures from driving.
That sounds all very tyresome.

I always thought that but in my TVR recommended pressure at the front is lower than the back so they get warm, maybe just for front engined rear wheel drive?
Rear wheel drive cars usually require higher pressure in the rear tyres than the front, I grew up with rear wheel drive cars so I’ve never questioned the logic or reasoning. Even with rear wheel drive and a hefty back axle, the weight bias is usually in favour of the front wheels, so this can’t be justified on a weight basis.
Use a gauge that’s checked against an accurate one, and follow manufacturers recommendations, that’s what I’ve always done. However, when using modern/ wider tyres on a classic car I always run them harder than the recommended figures but maintain the same front: back differential.
