Well, that was a first. Both tyres instaflatted on a particularly flinty descent this morning. Not going particularly fast fortunately. Really odd. Both tyres Gatorskins, front brand new with new tube, but rear has been on for ages. Inflated to 100psi (25mm tyres). Need to have a good look at the tubes. I'm guessing just bad luck - jinked sideways to avoid a pothole and down they went.

Top tip - always check both tyres are up before riding off  1

I know I'm swimming against the tide here but I've never had much luck with Conti winter tyres.  The Gatorskin in particular was a major let-down for me, failing to live up to its reputation in almost every respect.  I had flat after flat, the rubber seemed to cut very easily and I wasn't impressed with the grip either.  

Eventually I had to bin them half-worn and that's not like me.  I like to get full value for money and, as my lady will tell you, only rarely throw things away.

my experience of Conti winter tyres has been similarly unfavourable.  Except the latest GPs which I forgot to take off and have been fine...

I use Conti 4 Seasons in 28mm on my winter bike. In 6 years I’ve not had ONE puncture. Says it all for me, now in fear of disturbing the puncture fairies into action!

I'm in Tenerife currently, yesterday my rear tyre failed coming of Teide at speed. fortunately I was using my tubeless wheelset. I only noticed after 6 mile descent at 40+ mph in parts. The rear of the. bike was covered in sealant, it didn't rapidly deflate but gradually lost pressure. I rode the remaining 12 miles back to the hotel carefully without attending any further to it. a rapid loss of pressure would of seen me crash. Tubeless saved me and my ride from a long interruption  1

Blimey, good result you're ok, that could have ended up worse... How was the climb ? It's always looked like a beast to me..

The climb was, as Strava ranks it, 'Epic' beautiful weather, all the way up across the crater and again in the descent.
I'm going to try the longest climb here and possibly Europe Friday-eek

Only time I've double flatted is hitting a nasty pothole on a bend at speed on Tri bars.
I didn't realise both had gone until I set off again after fixing the first flat.

I don't p'ture too often, touch wood, but I have  doubled p'tured.  The time I remember was near the top of the Launde Abbey climb, a pretty short but sharp climb (lol, no pun intended).  I fixed the front and went to move off and noticed the rear was flat too, no wonder that was harder than it should have been  4

Pretty similar to me, except I missed the pothole (if I hadn't I'd have been over the bars, it was huge). Instant deflation, initially I thought I'd picked something up in a mudguard. Fields round here are a mix of flint, chalk, and clay plus its hedge-cutting season.

I hit a porche with my Gatorskins and it's still at 90 PSI. The rim deflated though. And the forks and frame are cracked... Tyre's still good.

In my experience so-called winter tyres are over estimated (and over priced).

Continental 4000 Sii - 3 punctures within a couple of weeks on a new bike. Changed to Durano Plus - double puncture a week in. Two flints had ripped through the tough protection layer about 2 inches apart. I rode the 5 miles home in 0 degrees as I had ripped my spare tube putting on the tyre which is next to impossible on my rim.

Then got my 3rd set within a few month - Specialized Armadillo. Easier to install but this year had 2 punctures.

On my slick racing tyres (Vittoria Zaffiro) no punctures in 3.000 miles and on my commuter bike with Vittoria Zaffiro Pro a couple of punctures in a year.

Conclusion; winter tyres are not worth the money. The Zaffiros are about 15 punds each, the expensive winter tyres cost at least twice as much.

If you think winter tyres are expensive, a couple of years ago I hit a pothole (a moment's inattention) and instantly flatted on two new Conti Competition tubulars, only about 1.5 miles from home.  Fortunately they were repairable otherwise £60 each!

Clinchers now for the winter, GP4kS2 and touch wood ony ever punctured when the tread was down to the wear indicators.
