I don't find good tires that expensive.

I think you are shopping on the wrong side of town, the expensive side of town anyways!
In Canada we get screwed abit on some product prices and tires are one of them. A set of "good" tires from Michelin would be $600+ for my Neon by the time I got out of there. From my used guy, $180 all in... For my $1200 car this makes more sense. I do get to pick the tires as well so I get something decent. I guess the good part about Canada is that almost any shop will repair anyones tires and there is no talk of liability, they will tell you that a plug may fail, and then you get to decide if you want to risk that. Seems like a good system!
It takes a bit of knowledge to go the used route but I've been in their tire lot and there are no old, very worn, or damaged tires so I think even the clueless don't ripped off.

On cars also it might well be that a new tire of a given make might be worse than a worn out one.

Hard to imagine 2.5 mpg difference though, that's a big change.......

That works for all tires. The less material there is to flex, the lower the RR. It's just more noticeable in big rigs as rolling resistance at highway speed is still in the 40% of total load, much more than cars.

I never realized the price difference was so high. My neon tires were $275 out the door with road hazard and the whole shebang. I would like it if people here sold used tires (we used to when I worked at a shop here in town growing up....but made it clear that there was no warranty on the used tires.) But I have not seen anyone doing it in better than 10 years.

It seems that it is better than them going to the landfill.
