Basic...here's a legit tire question while you're here...
Why are there standardized rolling resistance ratings for commercial truck tires, but not for passenger car tires?

Simply because there isn't infrastructure to enforce it realistically. If the trucking industry they have to pass DOT regulations on a multitude of things, tires being one.
EDIT: Upon rereading your question, I think I misread it originally. May I ask you to clarify what you mean by ratings?

There is, but the rating system has not been adopted in all parts of the planet yet!
See:
https://en.wikipedia.org/wiki/Tyre_label
This system lets you compare rollresistance, wet braking, and noise level.
You could look up Reifendirect.de or any other European source and compare tyre specs.
Costs nothing, but then you may not have access to the better sort of tyres common in countries with mandatory labeling. In those countries, tyres with inferior specs don't sell well at all, so makers have to get rid of their stocks elsewhere. Generally the better makers will put those tyre labels on all their products, regardless of where they are being exported to.
Sometimes it takes ages for the obvious to be adopted. The Universal Metric System, for example. Only North Korea, Liberia and the USA have not adopted it yet, although the world standard was established in 1861.

I believe the model of Enasave on our cars is technically the "Enasave 01 A/S". Looks like Dunlop uses that branding on other of their LRR models as well.

I see. So Low Rolling Resistance is kinda the same as saying small, skinny tires for fuel economy. People always comment on how small my Mirage's tires look.
I've had the Dunlops and now I have Bridgestone Potenza's on my Mirage. The Potenza's will squeal all the way to 100 km's an hour if I want them to - car's not broken, the alignment etc is fine, and they have 50% wear left. It's just the Bridgestones do grip different than the Dunlops did.

Canada was imperial, and now is officially metric. But many people in Canada still say 80 degrees for a good warm pool temperature, or 6'1 for my height, yet I don't know my height in cm's. 179 cm's tall I think. People use inches and 5/8" inch more than they would say 1.5 cm's or whatever it is.
Weird mix around here, with the USA being so nearby where I live in Ontario.. like they have Tim Horton's in Michigan, and Home Depot in Ontario. Or family in USA and Canada like me, as well as Holland.
