Im in the same boat. My rear tire is on the verge of being bald in the center but sides are good due to the "highway wear". In the morning on my way to work when my tires are cold, I get on the throttle in first my ass end breaks loose. Its this mostly because they are cold or the wear? Most of my riding is commuting to and from work. What tires would best suit me for my buck? I heard that Metzler makes a good tire for street riding/ commuting.
