This was added much later.
It was added 6 minutes later because you edited the question into your post after I had replied already.
Hamilton said his tyres were fine himself.
He also said his second set had 'gone' towards the end of the race, so either one set were awesome and would have lasted 45 laps but the next set died after 20 laps or Hamilton perhaps isn't the most accurate judge of his tyres condition whilst he's concentrating on racing.
And my other reasoning was provided: he was on Kubica's gearbox for many laps - not something you can do on marginal tyres. Moreover, Kubica himself questioned why Hamilton stopped for tyres when clearly he was having no problems keeping up with himself. Lastly, Kubica, Alonso, Massa had done similar paced races as Hamilton and they didn't need to stop for a 2nd time.
Do you not read any F1 news sites or forums? This stuff I've mentioned has been discussed hundreds of times.
What other drivers ask their teams during the race is largely irrelevant, they are not Hamilton or Webber, they had not been driving those cars, their tyre wear would have been different. It doesn't matter how many times it has been discussed on forums, more so how many times it had been discussed before Bridgestone commented yesterday when any discussion would have been pure speculation from all involved.
I really don't get why you're trying to argue against Bridgestone. I'm pretty sure they're clever enough to know what they're talking about and i'm fairly sure the guys who analysed the race tyres know a damn sight more about tyre technology than you or I do, so assuming they know what they're talking about, the only other option is Bridgestone are lying about the situation. Why would they do that?
Ultimately, all you have is speculation and why you think the tyres were fine based on what a few people thought at the time.
Bridgestone themselves have stated in no uncertain terms that the tyres were close to being finished on both Hamilton and Webbers car, something I can well believe given the manner in which they were driving.
You'll forgive me if I put my faith in the word of the tyre manufacturer who has analysed the actual tyres rather than the people speculating on the internet.
