Problem: Tyre temperatures can and will drop below the set air temperature (to appx min of 16oC) at standstill:
Example: achieved at events utilizing sighting/warmup laps and sat on grid waiting for timers to expire.
Conclusion: Tyre temperature probably shouldn't drop below air temperature.
Minor bug reported only for simulation 'completeness'.
+1 minor bug, but for simulation completeness i agree :)
+1
Hawk.
Not so minor if you ask me.
Agree but I based the label 'Minor' on the fact that the circumstances that have to come into alignment to make it a serious problem, will be rare ;)
Hmm, allow me to disagree. It just means that the thermal dynamics of tyres are way wrong.
So yes, getting the tyres to 16deg may need special circumstances, but maybe what you consider normal temps are ion fact 20deg off.
could it be related to some tyres constantly overheating on some bikes (hard front on the m1 for example)?
All I know for fact is the Air temperature seems to have no relation to tyre temperature (unlike Air temperature does have a bearing on track temperature and track temperature does have a bearing on Tyre Temperature), and I think it should.

What was the temperature of the air and the track?
air was cranked to max (38) as this would allow the result of this specific test to be determined quickest (starting from tyre warmer temp 60oC)*. Didn't note the track temperature sorry .
*Slightly counter-productive as the higher the air temp the slower the RATE of cooling. So Air temp does have an effect on the tyre (RATE of cooling) but it shouldn't go below air temp?
It was part of a series of tyre temperature testing to gauge how quickly a tyre would lose temperature (at a range of air temperatures down to 10oC) and the subsequent states for riders to be aware of at race start, and as a result of those tests, what techniques can be used to raise tyre temperature the fastest during lap1 or on a warmup lap.
Learnt a lot and pleased to say it all seems very realistic! From all of that, only this minor bug seems wrong.
Edit: just run the test (initial start) again and track temp at this air temp is 60oC. I appreciate for the test above it could have been +/- a few degrees either side of this. Ultimately the track temp has little to no effect on the tyre at standstill anyway.
