As far as I know tyre warmers have not been banned for this year. They were going to be, but I understand that the FIA just kept things as was.

[siskue2005]

yeah, i might have missed the tyre warmers ban.....whats going on guys?
Is it banned for good?

[axle]

I think they have limited the warming, not banned it.

I think they can only warm the outside surface, not the inside as was happening.

From the sporting regs December 2009 ..
"The only permitted type of tyre heating devices are blankets which use resistive heating elements. The heating elements may only act upon the outer tyre surface."

The new part is that heating can only be on the outer surface of the tire (not sure why the FIA continue to spell tire wrong ). So no carcass or wheel heating. How much will this affect tire performance? I think a lot because of the enormous sidewalls but I don't have to a way to do anything other than speculate.

I suspect we may see a lot more weaving and possibly faster warm up laps to get tyres to temp. Note, however that the cars will be heavier at the start so this extra weight at the start of a race may well return what has been taken away form reduced warming.

The effect may be most pronounced on low fuel, I suppose. Maybe we will see two out laps prior to a flying lap in qualifying as the norm now rather than just one?

The word tyre is not wrong, it describes a rubber component fitted to a wheel used for suspension and shock absorbing. It was designed and developed in Scotland
NOT Dreamland, so please do not tell the English how to spell.
Sorry Ciro but it annoys me when this happens.

My biggest concern is the penalty it will enact when changing tires in pit stops. It has taken about 1/2 to 3/4 of a lap to get tires "normal". I'm thinking that now it may be two laps or so. Therefore a tire change will exact an additional time of about 5-10 seconds. In any case it underlines the importance of chassis tuning for extended tire performance.

And lighten up autogyro, the spelling thing was said in jest with a wink.

In the U.S. it's spelled tire so you might catch me and some other people doing that

Yeah, it is certainly going to strike an interesting balance between cold new rubber and hot old rubber. I wonder if we are going to see cars passing freshly "re-booted" cars only to be re-overtaken once the pitted cars tyres have warmed up? A pit stop "dosey doe" as it were.

It seems as though you would have to gap someone by maybe 35-40 seconds to maintain a lead, and you know how tough it is to pass once cars are on similar footing. I think it could produce, perhaps, trains where cars are held up behind somewhat slower vehicles, like McLarens

I really don't think it's as much as this. I think we could see some surprises when it comes to strategy with more cars two stopping than we'd've thought. On the Merc I would say that it is something of a worry that they're still using the old front wing. It could be that they have something incredibly innovative they wanted to keep under wraps or it could be echoes of Mclaren last year with the testing with the 2008 wing. Knowing Ross Brawn I'd guess it's the former rather than the latter.

I hope they run new parts tomorrow.

This photo is of today's Barcelona test,the front wing as it seems has not changed

[timbo]

This photo is of today's Barcelona test,the front diffiuser as it seems has not changed

WTF is front diffuser?
Are we on LeMans

Now that's how you welcome someone to the site

He surely meant front wing.
