Great tire, solid in rain/snow/ice, super quiet, hasn't worn much yet
I have ~13k miles on these and Roamer is reporting 1.90mi/kwh on these (honestly within 0.10) of what the stock Pirellis but they are very quiet, more compliant and less harsh. I've rotated them every 5k and Tires+ is reporting no wear yet.
I'll update at 25k miles.

Uplift your R1S Experience
My stock Pirelli’s wore down at a dismal 28k miles. I decided to heed lots of online advice and did not replace them with the same tire but instead I chose the Dueller ATs. I went back and forth in my head between this and the Open Ctry III but these were way less in the end. Discount tire matched Costco. When I drove away with my new tires I was shocked. My R1S has never driven this amazing. Why did they ever put those crappy Pirelli’s on them to begin with? These tires are awesome. They’re extremely quiet and so far very grippy and steady in both rain and dry. I’ll see how they are in snow in 5 mos. I highly recommend these.
