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!
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.
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.
Aah, gotcha. I had thought that
Probably less these days
was in reference to this part at the end of the parent comment:
cars generally float around the 32 psi area
and I haven’t seen anything to contradict all the previous literature on under-inflated automobile tires being worse for fuel economy.
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
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.
You need to top off your blinker fluid to get to 100
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.
I guess lemmy has grown to the point that we’re just reposting Facebook car memes now.
That’s a pity.
I want to know the age demographics on Lemmy.
“Children” and “people old enough to be their grandparents.”
No in between.
Yep I think you’re right
I want to know what love is.
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.
97 psi. That guy is gonna die
Everyone is gonna die…
Technically correct.
I’m tyred of all of this now…
2/3 and 3/3 do not load for me. I guess I’ll never find out how out ends!
