Yesterday night on the Fourth of July, I decided to go for a biking session to set a new record on Strava. Upon my descent on this steep bridge, somewhere in the middle a 2-cm long metal nail punctured my fabulous Grand Prix 4-season tire . It happened so fast that my tire lost 110 psi in 3 seconds. Good thing it was my front wheel so that I could control myself to safety.

I was wondering, do you guys think this piece of iron nail could puncture anything in the market today? 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.
