Sometimes I barely chuckle at the funniest things. And then other times I can’t stop laughing over the dumbest shit. Like this 🤣

Sometimes the dumbest shit really is what sets you off. I remember losing it for a while when I first encountered “none pizza left beef”

I can’t believe it but there is a wikipedia page for it! https://en.m.wikipedia.org/wiki/None_Pizza_with_Left_Beef

Holy shit, 6.4 - 6.7 bar…

Is this even possible?

Road bicycles like the ones used in the Tour de France use pressures in the 120-140 psi range, but cars generally float around the 32 psi area.

Trucks often 60-100 though

Go to the truck stop and use the big rig hose. You’ll get what you want 🤯

Yep, 60/80 PSI on my work truck, but the tires are 12-ply.

Probably less these days as it’s shown lower pressures and larger tires can improve performance.

Which type of performance? Surely not fuel economy/emissions?

Source?

All the studies I’ve read (and my experience) show that narrower tires and higher pressures improve economy. Less traction and less ride comfort are the tradeoffs, respectively.

Not in a car… But 10 or 12 ply truck/tractor/trailer tires can run around 90 psi

I just looked it up. It seems that normal car tires will explode at 115 - 145 psi.

In not really talking about possible, I am more talking real world running pressure.

I’m sure you can air up a car tire but at 90 psi it would be so rock hard that travel on it would be extremely uncomfortable. Also you would risk blowing it out whenever you went over a big enough bump. The tire volume inside would deform and cause a massive pressure spike.

Tractor trailer tires are made with more layers of rubber and steel belting so they can safely handle higher pressures.

Yeah you can definitely do it with car tires for a short time at least, that’s how you check for leaks (overpressure to like 80 psi and put it in a tub of water, look for the bubbles)

I don’t think exploding a tire really counts as “undermining”

To be fair, you didn’t pass the natural selection if you died like that.

No, no, no… it has to be really cold air. That way when it expands as it warms you get 100%!

Keep going, make sure you’re not wearing safety goggles, also make sure not to read up on natural selection until after you’ve aired them up.
