X22 <<sighs wistfully>> My favourite compound.

I'll never forgive JLR.

I'd be very surprised if putting 300 plus horsepower through the tyres doesn't warm them. Bit like cornering and stopping. Otherwise how does heat get into the tyre !

Loton has the local council sweep the track and paddock several times a few days or the day before a race weekend, hence it is clean.
All the abrasion of tyres and then wrapping all comes to little as at the last few meters the tyres pick up small stones from the previous runner.
I just think it is all a ritual that many do instead of having a coffee and a bacon bap!
Each to their own, I'm not fussed, but I have taken the MSA passage as no wheel spinning before the start line as undertaken by some major venues already.
It will be a rule change for everyone, so the same disadvantage to everyone, if it is in fact a disadvantage.

With no tyre warming you will not get to the first corner and think where did this understeer come from.

I take it that, along with the current pre start and or drive by environmental (noise) scrutineering, there will, from 2018, be a scrutineer at the end of the run, checking that tyre temperatures are not above the ambient temperature and if so the run is disallowed in the same way that a competitor can pass static noise but have the run disallowed on drive by

cold tyres wont stop you getting to the first corner, whether you get round it is all down to how good you can drive.....

It doesn't say before the start, so it should apply to the whole run.

The rule states

"no manner of abnormally raising the temperature of the tyres/wheels"

Any increase in temperature that occurs whilst the tyres are being used for their intended purpose, ie the run, would not be considered "abnormal" and hence would be allowed.

I posted this almost 3 years ago, when Gurston banned tyre warming.....

Unless the rules have changed (maybe they have ?) I believe that unless all 4 wheels cross the start line, then you can have another go.

I personally would not do this, but competitors who are looking to flex the rules may choose to...
Just saying......
