Tyre Warmer Ban 2015

[Jersey Tom]

LMP1 doesn't use them. Indycar doesn't use them (road races or ovals). NASCAR doesn't use them. So you mean to tell me that 1) F1 engineers can't figure out how to get around this issue and 2) that the supposed best drivers in the world can't drive around the issue? What a joke.

There is much truth to this.

Wasn't Zinardi's crash due to cold tyres

Where is the point of banning the tyre warmers? We have seen where Pirellis tyre experiments lead to...

Reduction of costs? Stupid idea to do this with tyre warmers. In fact we have standard tyres, standard crash structure, standard ecu...
Why don't we have standard tire warmers instead of forbidding them? It is the same issue with the pit stop tools...why do we carry Helium round the planet and use expensive electric jacks instead of using standard tools?

[Bazza]

While I'm sure the sport will survive without tire warmers, I've never understood the drive to get rid of them. They can't be that expensive, relative to everything else the sport spends money on.

And if it is about the money, I've never understood is why the teams don't sell ad space on them. They're one of the few things in the race almost guaranteed to get at a few seconds' close up shot on camera.

The drive to get rid of them is purely about improving the racing.

This kills the undercut (see my post above), and changes the whole pit strategy dynamic to something less uninteresting, because of the short-lasting effect of cold tyres after a pit stop.

Money-wise you're right, the warmers are basically nothing in the budget of a F1 team.

[FW17]

If that is the case why have pitstops? They could just have tyres that last the race as in 2005. That would be a huge cost saving.

[lebesset]

quite clear that teams have been heating tyres above the designed temperatures to try for a short term advantage ...easy to blame pirelli for any ill effects ; at least that will stop !

How the hell is everyone talking about safety. What is unsafe about cold tyres. There is no difference to overusing the tyres. And if you want to make them safe. Allow traction control, ABS, automatic transmission, torque vectoring and all that stuff.

I can't hear it anymore that something is unsafe. Overdriving is unsafe. And therefore why not introduce a time limit so they wouldn't be unsafe at racing.

My friend said slicks have pretty much no grip on the first lap when they are cold and you skate all over the place and the car is really unpredictable, he has only driven up to GP3, though.

Nasr tested it in Bah, didn't work well, and with budget cap off the table it would be ridiculous anyway:

Every other series on the planet doesn't make use of tire warmers. Have they suffered because of the lack of them? I know you're going to say, "but F1 is the fastest ever!" LMP1 doesn't use them. Indycar doesn't use them (road races or ovals). NASCAR doesn't use them. So you mean to tell me that 1) F1 engineers can't figure out how to get around this issue and 2) that the supposed best drivers in the world can't drive around the issue? What a joke. The drivers will adjust their driving. The pressure increase in the tires won't be substantial because they are using Nitrogen already. The most that will happen is we'll see some guys locking up/spinning out on the out lap and drivers being instructed to not hit certain curbs on the way out.

LMP1 tyres use heaters. They're just ovens not blankets.

Yup!!!!!

I will add that the real problem here is not the tire warmers, but the tires themselves. As F1 has insisted that Perelli supply such fragile tires I suppose the argument can be made that the warmers are in fact a safety requirement.

Relative to dry air, nitrogen will expand substantially equally with temperature. However, though a lighter molecule, nitrogen will leakdown somewhat slower than dry air, i.e. than the oxygen in air, resulting in higher hot tire pressure with the same initial cold pressure. Of course compressing atmospheric air will include appreciable humidity. But F-1 teams would know better.

I believe that BE banned tyre blankets in GP2 because the noise of the generators required to run them at some circuits was a distraction for television interviews.

Perhaps they are to be banned in F1 for the same reason, or to reduce the cost of ferrying teams around the world, or it was not thought to be an issue in F1 because drivers have become accustomed to starting on cold tyres in GP2. Maybe all three.

Whatever the reason, it makes a bit of a nonsense of the effort & money spent on tyre guns, etc. to shave a few tenths off pit stops.

tyres cool considerably on long straights ,drivers already have to deal with that ; maybe the operating range would be greater without tyre warmers but F1 tyres which run at lower temperatures would have implications in the development of road tyres as well
personally I have always hated the artificiality of racing tyres with compounds like putty , rather see wider racing lines available due to the lack of marbles and better racing because of it

Highly doubtful, IMO. Completely different worlds.

Agreed. People who've not seen a sprint car before are often astonished how soft and sticky the tyres are to work from cold when they look at my tyres. You can move the tread like putty.
