Bridgestone Potenza Sport Enliten

Seen the review video done on the standard Bridgestone Potenza and they were well recieved for wet and dry grip but rated very poorly for rolling resistance.

Im looking for 255/50/R20 for a 400+ BHP SUV and i see the bridgestone Potenza Sport enliten is now an option.

With a Label of A for wet grip and A for fuel economy and 69db.

Does this new enliten moniker mean that the rolling resistance issue has been solved.

What exactly is this enliten rating all about and is this bridgestone now a solid choice?
