Sorry, no. I have closely inspected thousands of tires over the years but wasn't checking for the name of the manufacturer. If I had to guess I would say they were made by the Lowest Bidder Tire Company.[emoji1783]

[QUOTE=Arch Hoagland;5555079]"Inflation gauges should be calibrated often.

I calibrate my tire pressure gauges and torque wrenches twice a year or when damage occurs, I have my own calibration equipment but if I didn't I would pay someone to do it. Poorly calibrated equipment is no better than a bat to thump tires or an adjustable wrench and a piece of pipe to tighten your lug nuts.

That would eliminate Michelin.........

We saw the Space Shuttle in Houston and it had Michelin tires on it.

We have probably 1000 gauges in plant. I have installed 100s or R&R for calibration. Even cheaper Bourdon-tube gauges are pretty accurate when used within range when newish. After they flex thousands of times like anything they wear. Calibratable gauges will be back on if re-zeroed . So if you have a true gauge make note of of zero when you get it and use it. Pegging gauges will throw off pretty quick, vibration destroys right quick very low pressure ones like 10" water column those are best replaced with Dyer Diaphragm gauge .
Anyway is everyone really adding or lowering 2 to 3 psi 6 to 8 tires every day the temp is different.
Speaking about tires like the title there is a Space shuttle tire a nearby child's museum .Not as big as you would think but bead is about 4" thick about 200lbs . My family will be like how can you look at that tire for 5 minutes every time we come here lol.

What kind of plant do you work in?

I set my pressure in late spring for the summer and reset it again in late fall for the winter. Never touch in between.

The F14 Tomcats main landing gear tires were made by Goodyear

I wonder how much one of them would cost....

[153stars]

Aluminium powder and pigments. Aluminium powder is in solid rocket engines,furnace bricks ,pressed metal parts ,heat transfer for electronic chips. Pigment auto paint metallics, silver or gold paints,powder coating metallics and inks, the stuff in an etch-a-sketch. Either can be in fireworks.

Back down here on Earth.
If you have several gauges, test them against each other. If one is not near the others get rid of it. Otherwise replace gauges regularly.

RE Pressure gauge accuracy.

I have written a few times in my RV Tire Safety blog on this even included the results of "Gage Checks" I do at FMCA Int'l Conventions so we can see the results of digital vs stick vs dial gauges.

One post is specifically about the value of having your own "Master Gauge".



The 3 digital gauges I have been using for over 6 years have all remained at +/- 0.5 psi at a reference of 80 psi when checked against an ISO Certified Laboratory master Gauge so I am confident of their performance and accuracy. They cost less than $15 and proves that low or reasonable cost does not mean poor performance just as High cost is no guarantee of good accuracy.



Yes stick gauges seem to be the most likely to get off calibration the most as they get dirty or the stick gets minor scratches or "dings" that can effect the reading. Dial gauges can be hard to read as sometimes their markings are at larger then 1 psi increments. Hold the gauge at an angel and you get a different reading.


A good, reliable gauge is a good tool to have and use and as a tire engineer I would be pleased if I found people using gauges accurate to +/- 2% or better, so see if you can get and use a master gauge with that level accuracy.

Antilock brake systems typically look at the speed of each wheel during braking. And releases the brake pressure on that wheel if it shows it is slowing down much faster than the rest (it's skidding). Has nothing to do with air pressure.

Air pressure does affect traction though. So, if the tires are super hard (smaller contact path and less compliant to the small changes in the road surface) then they will not have the same traction. But then the vehicle is lighter so will always change speed easier too (less momentum). But the antilock brakes will still function the same and do the best it can with the conditions at hand.

Speaking of tires. Before leaving upstate NY I blew a tire on my toad. Right front on Equinox. I put brand new tire in its place (same make / size of other 3) in Florida now and should replace other 3. Will get 3 same again but wonder where I should place the
tire that now has 2000 miles or so. Was thinking on the back. Any advice ?
thanks

The usual advice is to place the newer tires on the rear to prevent "oversteer" in the wet which could result in a loss of control.
