I see max load and max pressure, what about at a load less than max?
Have a link for a lower load? On wait, I already posted that for you.
Yeah tires do have ratings, all you seem to care about is max. I gave you a link to a chart for loads less than max, made by a tire company and similar to many other tire companies charts, and you ignore it.
If this is how you are with tires I'd hate to see you react whe the fuel gage hits 1/2......
I would say it for the last time, but somehow I don't think it will get thru to you.
These are not MY opinions, all the data I am presenting is based on published data from vehicle and tire manufacturers. The only thing you are giving is an opinion, one that doesn't hold any water when presented with the facts.
Heck I even showed you the door jam sticker showing a 40 psi recommended pressure on an OEM LRE tires rated at 80 psi max, what more is there to comprehend? It's not imagination, it's fact pure and simple.
In your, and only your, opinion running a tire at a pressure appropriate for its load is under inflated if that's less than 90% of max. You are the first one I have ever read that statement from. It's NOT under inflated, it's called PROPER INFLATION.
Firestones issue was under inflation, but only because it wasn't enough air for the weight and NOT because it was less than 90% of MAX.
Quote: "The Commercial Vehicle Safety Alliance is currently exploring how to define underinflation for enforcement purposes. CVSA has already settled on a definition of a "flat" tire: 50% of the max cold inflation pressure stamped on the sidewall of the tire, e.g., 60 psi in a tire stamped for its max load at 120 psi inflation pressure."

Granted, passenger vehicles are seldom (ever?) cited for under inflated tires, so we have to look at the professional references.
