Hey guys! I own a 1973 Schwinn Le Tour that i use as my daily commuter. I am currently running the 1 1/4" Kenda K35s. I like the tire, however the roads are not the smoothest and i have the occasional gravel section/curb hop (sorry.) My commute isn't long but I am wondering how the K40s would fare, anyone have any advice? Will the width difference be noticeable? Any other suggestions? Thank you.
