Some of the Rocket guys seem to like Bridgestone Exedra Max tires (I'm considering a set for mine), but I don't know if they come in the right sizes for the America/Speedy. Funny how size can completely change a tire's performance. For example, a lot of the Rocket guys hate the Metzler ME880. I can only assume it has something to do with the larger sizes--the tread design or the compound or both don't scale well to a 240.
