This is just my two cents...If it was a choice between old crappy cracked tire, not riding or CS....Yeah I'd probably be on a set of CS's/Maxxis...But I'd also be asking myself, "Are these the OPTIONS ?!?" My experience has been that the CS's actually last a while, but the rubber compound they make them with is really hard, which means less grip. The other turn off for me was the tread designs of the front tires. It was like a half and half of vintage tread in the center but some kind of dual sport tread on the cornering edges, not real confidence inspiring...
Another recommendation I'd throw out there...Bridgestone Spitfires.
