Both of the series that you mention do not run a road based control tyre. I understand they have the option to run wets so their tyre performance in colder/wet conditions is not an issue.
I have spoken to the Pirelli representative this morning and they have confirmed that the reason for the recommendation of the use of the HR rated tyre is to do with cold/wet weather running. In cold/wet weather with lower track temperatures an HR rated tyre will run at operating temperature apreciably more quickly than a ZR rated tyre, given the weight and performance of the bikes to which they are fitted - equally they will cope with dry hot conditions without any problems.
The suggestion is that an HR tyre will get to proper operating temperature in a couple of laps max - you can push it from the race start - on a ZR tyre you might need 2-3 racing laps to get them up to temperature on a cold/wet day and that has safety implications, after all you are racing from the moment the lights go out - who would wait for their tyres to get up to temperature? |
Thanks for the explanation, its no use to me saying you must do this, or that, without an explanation. But still the question as to why they were allowed in the first 2 seasons, then vetoed what happened/or grounds for the change.
