Just a fluke. Pirelli have been fantastic in their first year of supplying so I don't see a USA 2005 scenario playing.

And why wasn't Vettel called to the back of the paddock after retiring? I thought you had to get to the interview section as fast as you could after retirement and not spend that time studying your data to see where you got the puncture.

But if it is allowed he deserved more respect from me. Most drivers just go straight to the back, but he spends the first half of the race seeing where and why the puncture happened.

Why all the BS ? The tyre had slid away from the rim where it was supposedly glued .. No glue ? OR Pressure much too low when 'cold'.

In nearly every other puncture the carcase gets shredded but the two rim seals stay in place, even in some high impact accidents too.

Time for either Pirelli or Red Bull to own up methinks.

My thoughts exactly Trying, so do they glue the bead to the rim?, and I wonder how much under operating pressure they are at the start, say the tyre cold pressures are set to be correct at 90 deg, if the tyre looses 25 deg on the green flag lap and wait for the start on the grid it would be approx 4 psi (0.28 bar), if RB push the low pressure lower limit (no really fast corners the so tyre lateral stability not as important as usual), they may have been running lower pressures than normal and it may have caught them out.....

trying. as far as i am aware, the wheels are manufactured by a reputable wheel supplier who also supplies wheels to other teams. the tyres stayed on the rims of ALL other cars, including webbers bull. so you can rule out a red bull problem. pirelli are saying that it was an outside influence, ruling out a basic tyre problem. they are suggesting, and not dismissing, cf shards from a previous event.

The FI tyres are not glued bonded or bolted to the wheel rim.
Pirelli supply the teams with tyres inflated with dried air at a pressure of 1.1kg/cm2.
It is the team's responsibility to decide at what pressure they run their tyres at.
Most if not all the teams use one of two allowed (by the FIA) gasses, nitrogen or carbon dioxide.

Red Bull running pressure WAY too low for increased traction at the start, came back and bit them in the A**
Pirelli not willing to point fingers, but they know the score.
Not the first time RB has played fast and loose with Pirelli spec's, remember the camber issue?
