Just bought a new set of race wheels, Hed Jet6 and Jet Disk, 2009 C2 clincher, and they came with 2 new tires, Continental Grand Prix 24mm. Are these better than the Continental Grand Prix 4000S tires I have always used? The 24mm tires are heavier than the 4000S, but are the new C2 rims from Hed better with the wider tires?
