Sometimes I barely chuckle at the funniest things. And then other times I canβt 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 βnone pizza left beefβ
I canβt believe it but there is a wikipedia page for it! https://en.m.wikipedia.org/wiki/None_Pizza_with_Left_Beef
Everyone needs a bastard of a friend like this
A bastard of a friend thatβll tell you to do something that can kill you?
Use cold air so itβll 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 youβre 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 Iβm not as tough as dad and it hurts my neck to do it that way, so I use my shoulder.
Anyway, donβt give up! You can get there, and a properly inflated tire can improve your mileage. Most people donβt keep their tires properly inflated and are just wasting money.
Holy shit, 6.4 - 6.7 barβ¦
Is this even possible?
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.
Yeah you can definitely do it with car tires for a short time at least, thatβs how you check for leaks (overpressure to like 80 psi and put it in a tub of water, look for the bubbles)
In not really talking about possible, I am more talking real world running pressure.
Iβm 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.
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 itβs shown lower pressures and larger tires can improve performance.
Source?
All the studies Iβve read (and my experience) show that narrower tires and higher pressures improve economy. Less traction and less ride comfort are the tradeoffs, respectively.
Keep going, make sure youβre not wearing safety goggles, also make sure not to read up on natural selection until after youβve aired them up.
