can somebody compare the efficiency of a tire with KEVLAR MB puncture protection to one with SMART GUARD puncture protection? I would like to buy the Big apple from Schwalbe, but Schwalbe promises a flawless puncture protection with the SMART GUARD in the marathon plus. I now have continental top touring and 1 puncture for every 1000km is not bad, but to much for me, (mixed road use). Are there other tires with exellent (almost flawless) puncture protection? Can somebody tell me how the Big apple (559-60) handels in the rain?
