I swapped out from very used RE92s to new. Wow, you can feel the tread move squirm around. When you drive on rain grooves the car moves with them.
My mileage went down about 6-8mpg. Tried pumping to 60psi but no difference.

My Used Potenza weight on rim = 21.7lbs ea.
My New Potenza Weight on rim = 22.9lbs ea.

But I know it's not the weight most seams to be the new tread.

used to get 71mpg to work and up to 77mpg back. 32mi each way
With the tires 62mpg to work and 68mpg back if lucky
Now with temps in the teens I struggle to get 60mpg. Very depressing after hitting 84mpg on long trips.
Anyway be prepared for the moving around on the new tires.
