Punctures. Usually I get little flint punctures which you don't even know about until you go to ride home and find the tyre is flat. Not the end of the world - at least you get to fix it in the warm. I used to get about one a fortnight on the 'bent, none on the wedgie which has armour-plated tyres.
In the last 7 days I've had five explosive punctures on the road. That's more than I've had in the whole of the rest of the time since I started cycle commuting, including the puncture I once had on a club run.
Last night I fitted a new tube and tyre. Foolishly I said to Mrs Jus Zis Guy that I hoped I could make it through the day witout a visit form the p*nct*r* fairy. Hah! Some hope. Less than 500 yards later Bang! and I was pushing the bike back home.
So I got out the wedgie, put air in the tyres and rode that. Which is a bugger because it's seriously windy, and intolerance for pushing the wind home was the reason I bought the 'bent in the first place.

Bah indeed. You must have done /something/ to arouse the ire of the P+nct+r+e Fairy. Go and say ten Hail Sheldons and stick this pin - | - into a photograph of Er+c M+rtl+w.

That'sa bit like me buying a 4x4 only to have the 4wd bit pack in just before all that horrendous snow we had last week....luckily, it wasn't too bad round these 'ere parts and I managed to use my bike rather than the car ;-) Dave.

Im sure you will have checked but is there anything on the rim causing the punctures?
No, they're all smack in the middle of the tread.
If you have a slightly splayed rim, the tyre blows off, the tube bursts (could be anywhere) and the tyre *almost always falls back onto the rim*. If the pucture is a long slash this is probably what happened.

Since it requires several minutes of spirited activity to remove these tyres from the rim, I don't think that's the problem ;-)
Actually I know it isn't. It's cuts in the casing, on the main part of the tread, around 3-5mm long. You can patch the tube and run it at about 80psi but one decent bump or inflate to full pressure and the tube blows out of the hole, so the tyre is doomed once it's happened.
Trust me, I am a connoiseur of punctures by now :-D
Next stop: the bike shop for a Park tyre boot or three.

I had the same problem. Changed the tyre and tube and still the thing punctured. The cause was poorly fitted rim tape after my LBS has replaced a couple of spokes and trued the wheel. The edge of the plastic tape was cutting the tube resulting in a puncture which looked like a split in the tube.
I was furious that my LBS had done such a poor job with the rim tape and received a refund for the new tyre and tube.

Plastic rim tape is a work of Stan. Velox make the One True Tape.

Guy's punctures are explosive. That means that part of the tube is outside the tyre casing when it happens.

Correct. Todays left a substantial tear in the casing, God knows what caused it. Unless it's that old tyre on which I hit a flint a while back and shoved to the back of the cupboard... Oh bugger.

After I was knocked from my bike in a bus lane, by a right turning car driver who did not look, I replaced my rims with double lined Mavic rims.
Unfortunately, the driver never paid up, as she had promised, for the damage repair.
and the p*n*t*re fairy has come-a-knocking at my door. bah. gotta buy some patchy stuff and may as well get a spare tube. running a conti grand prix at the front and a battered mtb heavy tread at the rear. looks very silly. Bah!

My experince of the hard yellow Michelin stuff is that it can't take the pressure of 150psi tyres, so the tube pushes through the spoke holes to give a "sphincter tea towel holder" [1] effect. Then it's only a matter of time before *BANG*.

You mean one of those clever holders where you poke the corner of the tea towel in and then can't get your finger out. The tea towel, however, drops to the floor as soon as you stop looking at it.
