does the gauge not shoot out with 125psi on the end
no, its capable of reading up to 150psi, the reading slide moves out about the same speed as a typical pencil gauge would when checking your car tyres.
I have a very similar version which is possible better marked for reading pressures than the one i linked to (going by buyers comments on amazon).
Juddian:
A suggestion for you all.Invest £8 or so in a suitable tyre pressure gauge, a tyre @ 75psi instead of 125 might look ok in the dark via torchlight, is it bulging slightly more than the others? dunno seems ok when you kick it, you can’t be sure unless you put a gauge on it, its heat that normally causes blow outs and low pressure overheats things quickly.
Punctures on truck tyres are often very slow, taking maybe several days to deflate enough to notice, and might only be actually leaking whilst driving due to normal tyre flexing opening the puncture hole a fraction with each revolution.I suggest something like this, amazon.co.uk/Alftek-10-150P … 330&sr=8-7
you can find other gauges but this type with the offset reversible connector will connect on every wheel type (including the inners on double wheels) that i’ve had to check, (some longer types where the twin connector isn’t offset are too long to fit on fixed super single valves due to centre hub) and the pencial type doesn’t need a battery so you won’t find it useless at 4am when you need the thing in 6 months time.
How common is TPMS ?
MY 7.5T DAF at work has it.
Juddian:
Well despite you being as wrong as possible on politics and covid in particular
Well, so long as we agree on the important stuff though!

Great idea.
I do know early types can throw up false warnings, so is easy to dismiss a genuine warning should it arise.
I expect newer versions to be more reliable, and to get better with time.
Never seen TPMS on a truck yet Stu, to be honest the latest motors are getting so bloody complicated re electrics that unless you had one for weeks/months i doubt you’d learn half of what features it has.
As an aside on tyres generally.
Boeing 747 Jumbo, 450 ton take off weight. Total of 18 wheels, so 25tons each tyre. Inflated to about 200psi (14bar) with nitrogen.
Spending hours at minus 40deg C, and very low pressure, then under full load heating briefly to 200deg C as it stops the 170mph aircraft! Remoulded up to 7 times.

.
But back to truck tyres, and from the above, I am having to rethink my position on remoulds.
"Retread tires? On aircraft?!
An aircraft tire carcass/casing (tire without the tread) is constructed super-tough. A carcass that is eligible for retread is a desirable asset; it has demonstrated that it can stand up to the abuse of airline operations.
Retreading a tire is less expensive than buying a new one. Some tires can be retread as many as 16 times! Airlines often retread tires less than the manufacturer’s limit as an added measure of safety. Another benefit: retreads have more plies than new tires so they can handle more takeoffs & landings.
Don’t retreads fall apart?
Let’s talk about commercial truck retreads for a moment… Big chunks of disintegrated tires litter the sides of busy highways. Is it fair to blame retread tires for the debris?
NHTSA Truck Tire Study
The U.S. National Highway Traffic Safety Administration published a commercial vehicle tire debris study. Researchers analyzed hundreds of tire debris samples to figure out why the tires failed. The results show that retread and Original Equipment (OE) tires fail at about the same rate.
The majority of truck tire failures (retread or OE) are not caused by problems with manufacturing. The number one cause of tire failure is “road hazard” — potholes, nails, car parts, and other hazards on the roadway.
The study lists the second highest cause of tire failure as “maintenance and operational issues” — overloaded trucks, improper tire inflation, and worn out tires. In other words, operators aren’t taking care of their tires."
I haven`t looked deeper into that, but probably will do later.

TPMS is fitted on our Iveco’s and it also shows the type pressures on the tanker wheels . If it’s not a standard item then maybe it was added because it’s for adr work.

Be interesting to see how it fares over time, from what i read the car versions using special valves tend to suffer from winter salt corrosion damage (as do so many exposed electrical systems), some systems work via ABS which might be slightly less accurate counting wheel revolutions but probably a more durable system.
What system does your Iveco use please.

The proportion of remould to new debris corresponds to sales of remould/new…which I find surprising and counter-intuitive.
.
Over half of blowouts caused by debris puncture, tyre deflates slowly-overheats— and blows.
Six and half minutes not wasted IMHO.

Careful, he`ll cadge a coffee or two for answering you! Mr Money is only a poorly paid, over worked driver, after all.
(And keep best your Peroni and any wines well out of sight too!)
iv noticed More blown out tyre remains at the roadside locally than ever.Near roundabouts Are these tyres made in China?i spose now we are out of the EU anything imported wont have to meet EU standards. im sure years ago when the BS standards were the norm goods were checked better. Reminds me a friend of mine works at an aircraft factory was telling me the great lengths the chinks go to funnel the substandard steel into that industry ,middlemen buy it thinking its german and it is generally but not 100% of the time
TPMS is…
All well and good providing, you can find somewhere that has an airline that hasn’t been stolen/vandalised/working and you can be bothered to mess around on a rainy forecourt trying to get another 20psi into a mid-lift tyre.
I’m confident 99% of day shifters would drive on, finish the job and go home. The trampers might be a bit more invested in the idea.
I do remember the Spanish outfits having a constant feed airline to their tyres but, I haven’t seen it in use for years.

Still in some use. See it in Spanish car transporters as well as other vehicles.
Twin wheels are more susceptible to a puncture letting one go flat and so doubling the load on the other.
Small wheels are harder to keep cool as less surface area.
Small twin wheels on a car transporter with possibly lots of body stopping air flows?

or two wagons parked up across the bloody thing on break, as is usually the case at Aust, renamed Severn Bridge, or any other services you care to mention

I used to have a line that coupled to the red line on the tractor.
I was told that it isn`t an approved inflation system so I promptly binned* it.

Seemed to me…
That it was vulnerable to being torn off in all sorts of situations thereby causing long delays. I’m assuming that’s one reason for it’s demise. On the whole it’s a good idea.

Agree.
Looks like it would be more trouble than its worth on a tipper or a truck on country lanes.
But on trucks going to bigger sites and using main routes, probably good.
The US…
Trailer system which is widely adopted seems to work well.
Much to this drivers and my surprise, completely flat tyres will inflate even if both beads are broken.

Fast forward to 12.50

Im surprised too! That system doesnt have those exposed arms that the system I`ve seen on the Spanish trucks.
Good find.

Surprised me too. I took one look and thought ‘yep that’s you guys fast asleep for another two hours until the Michelin man arrives’.

I’m guessing it’s an expensive system so, not widely specced on UK logistics4U fleets.

It’s useless always throws up tyre warnings when they are fine. It uses the ABS probably to count rotations of the wheels and those cheap ■■■ systems on every vehicle that use ABS for TPMS are a waste of space.
