So I picked up an old Schwinn Super Sport the other day to use as a commuter. It has 27 inch tires on it and they are badly in need of replacement. So I was looking around and there is not a very good selection of 27 inch tires out there. My commute is partly on a gravel road, partly on a county highway, partly on a gravel MUP and partly on city streets. So I think i need a cyclocross-type tire, but with lower rolling resistance and higher flat protection. Any suggestions? Any resourses on where to find decent 27" tires? Any help would be very appreciated. Thanks
