At the most billnuke1 summed it up

However all the others are correct too. Tires do get harder with age and less grippy. And why not just put new on them and not have to worry. But... if you are waiting for your new tires to come in the mail, then why not go ahead and ride them till they get here? Unless of course you do stuff that demands the extremes of performance from them.

I've had many a flat a 20 mph and just simply slowed to a stop to fix my tire or go home. I even had the sidewall of an old pair of gumwalls spilt like a zipper and the tube blow out and that was still no issue. Just a walk to the house.

I couldn't make the link you posted work. If you put the pic's in BF's Gallery, they still don't show in your profiles album.
