I just had the Yokohamas mounted today. My (likely overinflated) stock Contis were feeling a bit squirmy last weekend and were starting to show their wear. I'm setting those aside for the rainy day. So far with the Yokohamas I'm enjoying an entirely new relationship with the asphalt.
Re the mounting, I bought through Barnsley in Boulder, they matched Tire Rack's price and charged base labor price for the work.
