I plan on buying a new tires for riding this spring, but for the trip I will swap it back to the one on it now which is pretty worn but it should make the trip, I have someone who will mount tires for 5$ so I'm not worried about that part.
Id love to make the trip by bike and take a week to do it but I gotta use my car to haul all my junk. I'm wondering if it is like driving with a trailer or more like just a bit of extra drag and need to be aware that its there. My bike weighs about 500lb total.
