You can believe that if you like, but I guarantee you will find nothing in writing to support that idea.

Yes, it would be a fair assumption to say a tire with a UTQG treadwear rating of 180 is softer than one with a 400, but with the current complexity of tire construction when the treadwear rating is significantly closer (say 360 vs 400), the difference may be due to reasons other than a simple compound difference. It might be the case if, for example, you could get the 970AS Pole Position in 180, 240, 360 or 400 UTQG ratings. Something like Super Soft, Soft, Medium, and Hard compounds. That is not the case though.
