I am looking for a 'bullet proof' reccomendation for commuting tires on my road bike. I commute 28 miles each way through suburban/urban landsacape, most with seom sidewalks and berms where i can pick up road crud. I am looking for something that is not dog slow or heavily treaded so that my avg mph is dropped (it is 28 miles after all and I have to be in work on time), but I also have to deal with occasional rain here in Atlanta. Let me know if y'all have ideas on tire/tube/skin combination that would work without weighing 10 lbs.
