Dimension 255/50R19. For two weeks of operation, only positive emotions, after the Pirelli PZero Rosso is just a fairy tale. They balanced without problems, the largest load is 25 grams, I don’t know to whom it seems noisy for me so I don’t hear it, at high speed from 140 to 180 it keeps the road perfectly, driving like on rails, at low speeds it’s also super, not in a rut pulls. Excellent tires.
