I have had more than several leaks in my tires over the years. in fact just had one last week, had 85 p.s.i. to my eye ,it looked liked it would be too low, that it would be riding on the side wall especially in sharp turns. 75-80 lbs just looks like not enough, maybe I'm wrong.
Article on 80' p.s.i. max in tires what do you think?

Look at Michelin etc's websites, they have inflation guides there.
I agree though, I have NEVER ran 85psi in my tires, and always got even wear all things considered

Interesting article. I have 110 in all my tires and hate it. I use to run 90 and was a very smooth ride. Now I feel every crack in the road.

mgrantes Thanks this.

Lol...Took me a second to get it. -
I do what the guys that build the tires say to do.

After taking to Mike becket from MD alignment, i run 120 in drives and 115 in steers. Basically the inflation tables don't take into account going over 55, decently high running temps, weight shift durring braking etc. I've got no weird wear patterns on my super singles. Mich says 90 psi for my weight. 120 rides smoother, handles better, grips in snow better, gets noticeably better mpg, and makes the tires last longer. Under infltion is way worse for a tire then over inflation. The guys who run singles at 90-100 psi consistatnly get edge wear. I have non of that. My tires have used up 4/32 in 80k miles.

I have always ran 100 psi in all of my tires, never had any edge wear unless the alignment was way off. Never ran less than that because I wasn't comfortable with it, and more than that seemed to affect the ride negatively. Now that I run heavy I run what is on the sidewall, in case some DOT man wants to check pressure and write me a ticket.
EverLuc Thanks this. -
Confession: I didn't read the article. And perhaps I should before making my comment. But then I remembered that I'm just a truck driver and I don't need to read anything lol. That being said, I run intermodal freight (containers) and the max psi they'll use is 85 considering the type of tires they use....10/20's....awful tires. Sometimes a chassis will have the tubeless 11/22.5's which are great! Those ask for 110...but I only put or make sure it's around 100psi. For my tractor I just put in whatever it says on the sidewall. If I hauled consistent weight then I might read the article for tips on twerking...err....tweaking psi for that honey spot relationship. Kudos and envy to those who do.
