So, IMHO, a tire with a WR of 80 will PROBABLY be softer than one with 440 WR. This information, IMHO, can be a usefull part of the equation (as well as speed rating, reviews, recommendations etc) in choosing a specific performance catagory of tires - Extreme, Max, Ultra, Grand Touring etc.

Of course with race tires, actual testing is the only way to determine what the best compound is for that individual/car/race.

................uh, nevermind
Agreed, a treadwear rating of 80 ……..uh, doesn’t matter.
The system, and seat-of-the-pants, won’t always agree with reality. I had some Pirelli P5s years ago that were sensational in the wet, but confused me by lasting 55000 miles on one axle and 59000 on the other.
