Tires can cold tear. Cold tear is usually worse than overheating.
The riders have said the GP12 has the best front end feedback of any Ducati they've ridden, but if you look back at Rossi's flexible headstock on the M1, it didn't put heat in the tires. In general, a flexible chassis won't work the tires, but it depends upon how it flexes along various axes. Way above my paygrade. However, we have to consider the possibility that the front end feel on the Ducati was so bad, that the riders (other than Stoner) couldn't actually push the bike enough to generate heat. A flexible chassis, though less adept at heating the tires, could allow the riders to push harder, which could build temperature regardless of what the engineering data predicts.
Without data, we probably can't make a conclusion one way or the other. Ducati are still struggling with grip balance. Much ado about nothing, though, isn't it? Been going on since 2009 when the control tire came into existence, maybe 2008.
Re: Rossi & Burgess. Burgess' criticism has been going for a while now. Started last season in the Australian TV interview when Burgess said that Rossi needed to ride the bike and stop worrying about re-engineering the machine (or some such). These remarks aren't a new theme.
