I was wondering, do you guys think this piece of iron nail could puncture anything in the market today?
Yes.
I doubt there are any. It's sad that I never got to fully assess this tire that I bought for $70 and it only had about 250 miles in under a month. Perhaps the sharp nail was sheer bad luck.
1. The tire could be fine if the nail didn't damage the cords.
2. Buy your continental tires from your favorite UK supplier for $35-$40 each.
3. Ride GP4000SII tires because they have much lower rolling resistance than the GP4Season.
