Just recently reinflated my tires to 55+ psi (cold). Been doing that since 2010 or 2011. My tired run and run. No blowouts. I rotate tires pretty occasionally. Wear is fairly even. Just my experience.

i used to ride on 52-54 psi, but on my set up (spacers, low profiles , upgraded side wall tire size) i started getting way to extra wear in the center of the tires and none on the outside.
so just make sure you are watching you wear closely if you have anything from stock set ups.
i am running low 30s now to compensate for the bad wear I was getting, economy...no not really, but you could look at going through tires quicker as a waste of money too and at the end of the day it is economy to save your tires and get better conistent tread wear.... blah blah....
kinda off topic, but ultimately just watch your wear when messing with tire PSI
i didn't notice too much MPG from going to low 50s by the way, and it was pretty stiff and rough.
not worth it to me, id rather coast and have better driving practices for MPG, and aerodynamics

I use the highest tire pressure I can and still get even tire wear. With Michelin Energy Savers I'm using 50 psi on 225/50-17 on my FORD CMAX

Let's bump a tire pressure thread and have Youtube serve it:
Optimal tire pressure suggested, plus nitrogen not worth it but good tires are.

Pretty much everything in that video is wrong. It would be best to completely ignore it. Normally I'd write a point by point rebuttal, but I'm having Internet problems, so I'm using my phone. If you want me to do a point-by-point, let me know and I'll do it when my internet comes back and I can use my computer! |

I'm just posting whatever I can to keep the forum active.
What about everything that's not pretty much everything? Good tires better than cheap tires?

That's opposite to Youtube, which wants me to watch more and more of the same thing. Here're two more
Best tyre pressures for extended life, boosted safety & maximum grip | Auto Expert John Cadogan
I got bored by this one with it's three-minute commercial, but it has Auto Expert right in the title.
AVOID These 5 Tire Brands (And 10 That Actually Lasted 60,000+ Miles)
Summary at https://youtu.be/KFsRaImfVBo?t=1929. I liked this one better -- the AI narration is listenable at 2X and it's data driven.
I like the cost-per-mile, but I don't know if the figures were normalized for tire size (and surely assumed four tires in all.  ).
