At 140 psi, why would there be any difference? The point of pneumatic tires is that they conform to the road. Set the pressure high enough and they stop doing that to any useful extent - unless the rider's weight is 250 lbs.

Oh, there's a difference. You just can't feel it, apparently. I don't want my tires to "conform to the road." That's too much friction. If I want my ride to feel mushy, I'll ride a mountain bike with tires at 40 psi.

Expect that claim to be triggering as well. Current fashion is to ride mountain bike tires at <20 psi. I’ve been told that I simple “cannot ride mountain bikes with tires pumped up that hard”…even though I ride mountain bikes like that all the time. Rims are more important to me than a squishy ride.

I just stretched an assumption to bicycle tires.

Max pressure is 65. Inflate to 51-52 psi. Liking them so far. I don't ride my mountain bike in the mountains. Just in the suburbs, riding over curbs. Don't like to bunny hop, broke too many spokes. My mountain bike isn't made for jumping, but great for my purposes.

Since motor vehicles were brought into this from the very start of the thread, I'm going to say that 80% is definitely just bunk.
My truck tires are spec'd for 80 PSI max pressure. I'm certainly not going to ride around every day with them inflated to 64 PSI. 36 - 42 PSI is what I use normally. When I'm loaded down with cargo and the tires are obviously out of the proper profile and shape to be riding safely, then I inflate them to higher PSI. Sometimes with a trailer loaded up and a lot of tongue weight on it that sometimes is almost 64 PSI or has even been more.
Same thing applies to on a bike. It needs to be inflated to the proper pressure to give the ideal shape and contact patch. And other things come into play too, such as how one perceives the handling of the bike at a particular pressure and whether or not one regularly gets pinch flats.

^^^Yep. And as with bike tires, charts exist to determine pressure based on weight of load. Or we can just go with a WAG or phase of moon or chicken entrails.

If you want your rise to feel mushy and actually be fast, you'd inflate 19c tires to 118 or so. Otherwise the who bike has to roll up and over every pebble and crack, which is slow.

There’s nothing wrong with narrow tires, of course. If you prefer the ‘connected-to-the-road’ feel of a racing bike, then you’ll be happier on narrow tires. If your friends tease you to get ‘with the program,’ remind them: narrow tires are not slower than wide tires – they just aren’t faster, either.

They’re not “over pressure.” Listen—you ride at whatever pressure works for you, and I’ll do the same. I hope you win whatever race you’re in.

Stuff like this is what makes me suspect your credentials. You—seriously—don’t think there’s a difference between pneumatic tires pumped to a high pressure and solid tires? You think they ride exactly the same? Do you also think they weigh the same? Have the same responsiveness? Please tell me you don’t. I’ll lose what little respect I still have for you.

Why are you talking about speed? You've stated multiple times that you don't care about speed, only that your ride feels fast.
Those two are different things. Overinflated tires feel fast while properly inflated fast tires feel like very little. Because they conform.
