On my way to work this morning the rear end started to wiggle, almost like when you break a spoke.
When I got to work I checked the spokes to see if I could get home tonight and the spoke are all fine.

It's the thread that is coming off the tire, it's separating from the body of the tire!!! Just like a cheap recap!

Do they recap bike tires? I know they still do on truck tire and cheap car tires but I don't know if they do with bike tire

It's a Specialized tire that came with a specialized Allez 2005 that I bought for parts (cracked frame) last summer. I use that wheel as a spare when my regular wheel as a broken spoke or something so I never bothered with the tire as the thread is like new.

So I went to the lbs a bought the best tire I could with the little money I had this morning (40$) I got myself a Vittoria Rubino 700x23 60 tpi rated for training that should give me good mileage (9000 kms last year so mileage is important for me) 32.99$ + taxes.

By the way here's a few pics of the defective tire



Anyone ever had that?

Never had that happen, but many tires are made with several different rubber compounds bonded together, so I can see how it might occur. Did the tire look weathered or worn in any noticeable way?

Never experienced a tire failing like this If it were the front tire, the situation could've been really interesting. I'm not aware of any bicycle tires being, "retreaded" like a truck tire

Not at all but it's still an old tire, It came from an Allez 2005 so the tire is at least 8 years old.
But the tread is like new.

Looks like the tread separated from the casing, not real surprising for such an old neglected tire.

Tires do have a shelf life and will go bad over time just sitting around.

Working in the automibile industry I know about car tire shelf life,. I just didn't realise/thought about that I was riding on a 8 y/o tire.
The thing is that my old bianchi 1984 is presently on old vintage michelin tire I bought on the internet (don't really know how old they are) but they are looking very good and they perform very well.
On the DOT number of every car tire you have the month and year of fabrication but do you have the same on bike tire?

My Bike is only 4 months old, like a week a go my bike tire completely crack in two different places, of course it had to be replace. So I've manage to get a better tire at a bike store, looking forward to get the front tire soon to avoid the same problem in he near future.

Had a decent looking tire explode in my face as I was pumping it up at less than max PSI. No idea how old it was but probably over 5 years. It was also a Specialized tire but I wouldn't hold either of these instances against them. I have also seen, though not experienced, the separating casing on tires that were likely younger than yours. Who knows how they were stored? I wouldn't trust my well-being to a set of tires that had spent 5 summers in a hot garage.

You made me remember that I have an aging set of back-up tires I should probably give to a non-driving friend down the street who has been riding on knobbies turned slicks for a while.
