Ride on Panaracer Crossstown Puncture Resistant tires? You better watch out, I've had one blow out, and another one nearly did due to a defect in the tread.

The damaged area that I found before my front tire could blow out

I purchaced and installed two tires just prior to Cycle Oregon 2009.

Less than two months later, my rear tire blew out while I was commuting home. The gaps between the tread had cracked and the tube managed to squeeze out. I felt the tire failing as I was riding. It suddenly started "thumping" like I was riding on concrete with seams, despite the fact I was asphalt. Before I could stop to inspect for something stuck in the tire, it blew.

I carefully checked the front tire, but it was fine. I took the destroyed tire back to REI, and was refunded the purchase price.

Last week, I just pulled up to my door, and as I was getting out my keys, I noticed that the tread was seperating on the front tire.

The defective Panaracer CROSSTOWN Puncture Resistant tire

I noticed cracks that allowed threads to show all around the tire, it was not a cut from debris. I took the tire back to REI and again I was refunded.

I recommend anybody who uses these tires to carefully look for the cracks I found, and get the tires replaced before they have a blow out on a ride. I'd also recommend that the manufacturer recall them.

Be Safe Out There!

From my own experience, speaking insolently of the puncture fairy's abilities will invite swift rebuke. Even the slightest mention of your lack of flat tires may result in a response before you finish speaking...

Printing "puncture resistant" right smack on the sidewall just seems like a recipe for disaster!

Ya, that definitely looks like a manufacturing defect.

But this is the modus operandi of the bicycle parts industry.
Aren't you willing to trade grams of tire for pounds off your face?
