Is it being pushed by the industry or tubeless tires really roll better?

Have anyone seen rolling resistence test between various tire widths and preassures? I really would love to see for example comparison of one model of a tire with 23, 25 and 28 mm widths (Gp4000 S2 for ex.) with tire pressures from 4 to 10 bars. Every test Ive seen so far was for 25 mm tires.

But instead of 28mm tires on a 17c rim, you should use a 21c rim with a 25mm tire (real width 28mm): Less weight and the tire will be stiffer and you can run the same low pressure as on 28mm tires. AND no squishy ride, still feels like a road bike and rolls great, even on bad roads.

Wonderful thanks! My rims have 17,9mm internal width and with 28mm GP4kS2 the real tire width is 32mm! But I really cant see a problem with that. 21mm rims like these i just spotted would be great tho for sure. Mabe some day because I already have theirs rims

A lot of data on bicyclerollingresistance.com contradicts the testing in the BikeRadar test. Just at a glance, the Vittoria Corsa came out as one of the slowest tyres in the BR test, but BRR.com has it as one of the fastest.

Interesting metrics you got. My rim is wider than yours at 19.9 mm (internal) and my 28 mm Continental GP 4000s measure 30mm. You should check your caliper for accuracy.

In the test which Beaver posted is meassured width 31mm for a 17C rim (17 mm I assume) with the 28mm Conties. So there might be someting smelly with you meassuring equipment
Anyway the tires might be streching out a little after some miliage. Mine are almost wore out.

Mine are Conti 4000s II 25mm on Mavic Pro Carbon SL C's and they come up at 28.2mm.

I do not like the feel of 25mm tyres on my 17C Bora clinchers, they just feel and look (27.5 mm inflated to 85/90 psi, although I did measure one worn set at 26.8 which was odd but they were a few years old so maybe a different manufacturing process) too big. 23mm tyres (GP4000Sii = 25.3 mm inflated to 90/95 psi, Michelin Power Competition = 24.8 mm) feel fastest on them and most comfortable. I am using 25mm tyres on my narrow 15C Shamals purely because they do have more grip on wet / cruddy roads but I don't like the feel on high speed descents on dry roads, too much movement, the Boras on 23mm's are amazing. I run the 23mm tyres at 90 psi front and 95 psi rear.
Surely the point is what external tyre width is best not what it says on the label. a 23 mm tyre on a wider (17C+) rim is wide. 10 years ago a 25C tyre on a normal 13c/15c rim was considered huge!
For me the 25mm's were too wide and even if I could fit them the 23mm's are plenty comfortable enough as more aero so pretty much perfect on the Boras, but the point being that a 23mm on a 17C rim is pretty much a 25 on a 17C rim, just more stable.
All measurement with a UKAS certified caliper!!
