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

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"
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

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 π€―
Yep, 60/80 PSI on my work truck, but the tires are 12-ply.
Probably less these days as itβs 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
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.

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.
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.
Jesus Christ! A friend of mine exploded a mountain bike tire when trying to inflate it to 100psi, assuming it would be the same as on his racing bike, he said it went off like a grenade. I can't imagine what a car tire would be like.
I've got one better... I used to work in a bike shop. When building new bikes, it's common to overinflate the tires (to get the bead seated nicely all around) and then let the excess out. I did that one day with a flat repair, and blew the side of the rim off, it had been worn so thin by the brakes. (This was many years ago, before disc brakes were common)
Also, we had a deaf girl working with us. If someone exploded a tire (it didn't happen often, but it was more than never) it would startle her too, she didn't hear anything, but she said she could feel it.

You need to top off your blinker fluid to get to 100
Just swerve on the road to warm up the tires like a race car driver.
I guess lemmy has grown to the point that we're just reposting Facebook car memes now.
That's a pity.
If it's funny and I don't have to go to Facebook, I have zero problem with it.
People are allowed to like what they like. Please don't gatekeep.

Someone please confiscate their keys so nobody else gets hurt
They were just overclocking their tyres
Just explain to them they overlooked it is in psi and not % and all parties will be safer. It was probably a joke by the creator and by you.. but ignorance isnt bad, it's an opportunity for improvement. -Brought to you by Hallmark
