I thought the problems were made worse by it being cold?
Actual degredation increases in high temps, as in the rubber melts and wears down quicker, more chance of blistering and other problems. The cold means the tyres don't heat up, don't get gripping and slide through corners, which introduces graining and can do so VERY quickly. The graining doesn't really seem to go away, while proper tyre wear seems to take at least some time under normal circumstances. The tyres seem worse this year in that there is a very narrow zone where the tyres work, too cold, too hot, tyre go bye bye. Tyre just right, boom, it will last forever(not really, it just won't have as many issues).
this_is_gav. I get what you're saying, and the overall best car should win, but the tyres are still a joke.
We had a situation in the first race where Vettel lost time by trying to pass Sutil, he may well have improved his final position in the race if he'd held 4-5 seconds back from Sutil and just cruised around, the tyres wear faster as the aero is way less effective following people meaning less grip in corners and more sliding, more tyre wear, more graining. Vettel's pace dropped off not because Sutil had the faster car, but because Sutil was in clear air and Vettel wasn't. One of the reasons Kimi's race went so well after 7-8 laps was he wasn't that close to Ferrari before Vettel/Ferrari's pitted, he didn't follow too much for too long, and also went noticeably slower in qualy(took less life out of those tyres). After the other guys pitted, he was often running in clear air, while others were often following.
The tyres being so poor and working in such a narrow window means cars are punished for pushing to catch the guy infront, they are punished for trying to pass the guy infront, they are punished for trying to qualify at the front. This isn't conducive to good racing.
So for me, the tyres have to be FAR better, I want to see the best car over a race win, not the fastest, but if that meant Kimi's qualy pace sucks, his race pace is great, but more often than not he's punished for trying to overtake people, thats bad. If Vettel or whoever else has most races with a lead, clear air and by default better tyre wear in most situations/races, its a stupid advantage. Don't forget that Vettel was doing well till he pitted and followed around a guy on a different tyre/strategy, ruining his race completely, while Kimi ran a different strategy meaning he stayed out longer and had more air when he did pit.
Ultimately if 3 other cars went with different strategys, Kimi could have ended up behind Sutil, had his tyres ruined, and Vettel was in clean air and run off to a victory.... this is what I hate about crap tyres.
