I am commuting on my bike and I have Michelin PRos. It's a waste using these tires where there are no curves I'll be taking at high speed. What's the most punture proof tire out there? I don't care if it is heavy or has a lot of rolling resistance. I just want a bulletproof tire as possible....fixing a flat is not something I want to deal with after a stressful day of work. Again, I'm not concerned about rolling resistance or weight so I'm not weighing those into the purchasing decision. I just want something as bombproof as possible.
