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.
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
Yep, 60/80 PSI on my work truck, but the tires are 12-ply.
Go to the truck stop and use the big rig hose. You'll get what you want 🤯
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?
Yes fuel economy. Energy expended per distance traveled or power needed to maintain a given speed. Just the fuel in this case is burned by your own body.
At world class levels, a few watts here and there will make a big difference by the end of a race.

Not in a car... But 10 or 12 ply truck/tractor/trailer tires can run around 90 psi
Don’t slash ‘em
Unless you want to end up in a watchpeopledie sub
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.
Right, you would likely pop a tire on your friendly neighborhood pothole. Even if you were lucky and avoided all of that, the tires will bulge in the center, drastically reducing the contact patch with the ground and you'd have probably 15-35% traction compared to proper inflation.
Use cold air so it'll expand in the tire. Alternatively heat the tires, put them in the sun.
You need to inflate it to just over 100 so that the air that escapes when you pull the inflater leaves the tire at 100.
An easy trick is to press in on the tire with your shoulder as you're inflating; really push into it, and it adds just enough to offset the air loss when you stop inflating. Dad used to use his head, and that worked great because the smaller surface area of the top of his head meant more PSI, but I'm not as tough as dad and it hurts my neck to do it that way, so I use my shoulder.
Anyway, don't give up! You can get there, and a properly inflated tire can improve your mileage. Most people don't keep their tires properly inflated and are just wasting money.
Everyone needs a bastard of a friend like this
A bastard of a friend that'll tell you to do something that can kill you?
To be fair, you didn't pass the natural selection if you died like that.
“My job is to enable you to undermine yourself.”
I don't think exploding a tire really counts as "undermining"
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"
Haha me too!
what does that mean
I can't believe it but there is a wikipedia page for it! https://en.m.wikipedia.org/wiki/None_Pizza_with_Left_Beef
