My first Flat

I got my first flat today on my new bike thats suppose to have puncture resistant tires.

Of course the flat is on the back tire. The only good thing is it happened when I was done with my ride. I'm going to attempt to change the flat. Tomorrow I'll stop by my LBS and get some tubes. Wish me luck........

You can do it!

Thanks. Dont know what I ran over, I rode about 9 miles, went over some railroad tracks(twice), I also forgot to inflate my tires before I rode. I inspected the tire and didn't see anything.

Have you changed a flat before?

Check the area around the valve stem--that's where all my flats have occurred. The rubber there just separates.

Good luck! (And I'm pretty sure the thread title should be a children's book or something.)

No never changed a tube before.

I asked because I didn't want to throw out random, unrequested advice to a seasoned flat changer. So I'll start by saying that I have never changed a flat because I've never had one. I have all the supplies and have taken several (over the years) free clinics regarding flats. The best one was the most recent one and the instructor emphasized to theck both the inside of the tire once you have it off the wheel and the tube is out, and check the outside of the tire. Try to find what caused the flat, because if it's in there and you fix the tube, put it all back together, you'll just get another flat. So look and feel the inside of the tire for the culprit.

It's a good idea to check tire pressure prior to every ride. Is you have presto valves you lose about 3 pounds of pressure every day! Surprising, huh?

Let us know how it goes.

Got nothing to do with the Presta valves. Those actually seal a whole lot tighter than Schraeder valves - with Schraeders, the valve cap is actually what keeps the air in, and we all know how "airtight" those little pieces of plastic are.

The air goes out through pores in the rubber. Lightweight tubes tend to be more porous, and also are more likely to have Presta valves. That's all ...

Anyway surgtech I can't believe you've been riding all this time and have NEVER had a flat! You'll be fine, it's easy.
