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?

[-] BackOnMyBS@lemmy.autism.place 15 points 4 hours ago

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.

[-] CookieOfFortune@lemmy.world 2 points 2 hours ago

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

[-] _thebrain_@sh.itjust.works 26 points 6 hours ago

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

[-] mrsemi@lemmy.world 3 points 1 hour ago

100 psi is standard on semi truck tires.

Steer tires specifically are sometimes 110 or even 120.

[-] HairyHarry@lemmy.world 30 points 6 hours ago

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

[-] _thebrain_@sh.itjust.works 2 points 1 hour ago

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)

[-] Rhaedas@fedia.io 23 points 2 hours ago

You do not need to overpressurize to find leaks. This is dangerous advice, as a tire blowing at even lower pressures can kill you. And there won't be any warning before it does.

That makes sense. Thanks for explaining!

[-] ayyy@sh.itjust.works 9 points 1 hour ago

Do NOT do this!

Unless you want to end up in a watchpeopledie sub

[-] Dave@lemmy.nz 39 points 7 hours ago

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

[-] moody@lemmings.world 4 points 2 hours ago

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"

[-] pyre@lemmy.world 1 points 49 minutes ago

what does that mean

[-] Im_old@lemmy.world 19 points 7 hours ago

Everyone needs a bastard of a friend like this

[-] aeronmelon@lemmy.world 12 points 6 hours ago

“My job is to enable you to undermine yourself.”

[-] Maalus@lemmy.world 4 points 5 hours ago

A bastard of a friend that'll tell you to do something that can kill you?

[-] cheddar@programming.dev 1 points 4 minutes ago

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

[-] Jourei@lemm.ee 14 points 7 hours ago

Use cold air so it'll expand in the tire. Alternatively heat the tires, put them in the sun.

[-] sxan@midwest.social 7 points 4 hours ago

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.
