Holes in the tire itself

So I went out for the first ride in my new (and first "serious") bike (Caad9) and I blew two rear tubes in about 15 minutes.

These tubes blew in different spots around the wheel, I'm pretty sure from hitting glass or a rock. There are corresponding holes in my tire where each tube broke.

So now, I have two small holes in my rear tire (one about 1cm long, size of a thumb-nail clipping maybe. The other is smaller. The smaller one has torn some of the inner fibres of the tire, where the first one has just ripped the outer rubber part).

I have found copious amounts of info on repairing TUBES, but I am wondering about the tires themselves. It looks as if a new tube mught protrude from one of these holes and just cause bad things.

Is there a way I can patch the tire itself? Can I ride without a patch? Should I just buy a new tire?

You can try putting a boot in the tire. I have used a piece of sidewall from a worn out tire. Tape or glue in place, if the tire
hops when you ride it either lower the air pressure a little to see if that helps or throw the tire away and start over.
I wouldn't do this on a tire I was going to use on bike I rode lot.

What you describe don't sound like holes in the tire; rather, it sounds like damage to the tread and...in the second case...some damage to the tire casing ("...inner fibres of the tire"). If the casing is intact, you shouldn't even need a boot; the tube will not expand through it. However, too much damage to the tread will make the casing...and your tube...more vulnerable.

Is it possible you had snakebite flats due to impact (e.g., pothole) rather than a puncture from an object piercing the tire casing? The damage to the tread and torn casing threads you describe makes it sound plausible. Proper tire inflation and hazard avoidance are necessary with road tires.

In my opinion patching a tire is an emergency repair. I would pitch the tire.

You can patch um and get many miles from them.
Roy had this flat at 400 miles. Booted and rode another 9,100 miles.

The cm hole is probably too big to patch. I'd give it a shot. Worst case...buy new tire.

Booting can work extremely well. Other booting materials: short piece of rim tape, mylar wrapper from Powerbar or equivalent, dollar bill, etc.

I'm impressed that you were able to boot that tire successfully, with the entry wound so close to the contact area of the tread. Well done.

It's actually easier to boot a tire near the center of the tread. I'm impressed the boot held on the hole so near the bead- that's a nasty spot.

Mike, your OEM tires are listed as Vittoria Zaffiro. I'm with Tortuga- if they're that fragile, save your pennies for some sturdier and possibly fatter tires. Light tires might be fast- but stopping to fix flats can make riding seem like torture. Bike rides should be fun.
