Dangerous Defects in Panaracer CROSSTOWN tires!

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.

Exposed threads showing in the cracked rubber.

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!

PS: I posted this to the Advocacy and Safety Forum too.

Thanks for telling us. I just bought a secondhand bike from eBay, it so happens to have a 32mm Crosstown at the rear and a 32mm Infinity Armadillo in front. Both tyres look a little old but there's still plenty of thread left. I'm wondering if I should replace them, with say Continental Sports Contacts? I have Gatorskins on my primary bike but I don't think I can afford to buy another set for this bike...

looks like there are some serious skid marks on the tire in that first picture, and major balding going on in the 2nd too. If that's the case, then it's not necessarily the tires fault. perhaps they wear too quickly, soft compounds often do, but perhaps a riding style issue too. I ride a fixie, and try NOT to skid to a stop, it creates bald spots. I rode with many other fixie riders in my time, some loved to skid to a stop (it is cool ya know), and then they'd complain that it was sooo expensive replacing tires all the time. Well duh, don't skid.

I'm not saying you do skid, just that your pictures seem to show skid marks and slightly uneven wear.

Tread separation from the casing is not an uncommon occurrence, especially on puncture resistant tires. Large objects can also cause tire damage resulting in a blowout as you described.

The wear seen in those photos is a concern, if the tires have low mileage and normal usage.

Wow, I've had Crosstowns on my commuter for more than 2,000 miles, and they've been really great. Mine are the 26x1.75 models.

Maybe REI got a bad batch?

Wow, must be a bad batch. I bought two pairs of Performance Gothams (A re-branded Crosstown) in April '08 and have put over 5000 miles on one set without a problem. I'm using the 26" version, but I even overinflate them to 80psi. What pressure had you been running the 700x35's at?

Actually, that's a casing problem, not a tread defect per se.
