I replacer my old stock tires last year with the Bridgestone TW 203 and 204 mostly street tires. After a thousand miles I decided to go back to the Tw34 and try a Kenda 270. I actually like the Kenda 270 better. I guess the knobby tread makes the bike want to always track straight where as the more street wise tires felt less stable. I never liked riding with only one hand where now it seems to hold true and straight. Also, no more or no less vibration and actually felt they held the road better. I ride on lots of rough back country paved farm roads and even on a good road I couldn't tell any difference. The best part is riding in grass or trails I have much better traction and feel. I think I set my own personal record of 45 minutes to change out both tires and fire up for a teat ride.
