Hello.
The last few days I had the feeling that the grip as a function of temperature has changed a lot in the patch S.
Today and yesterday I ran tests on this.
Both tests are run with the FOX on Fern Bay Gold, because I have a fair amount of experience with this combination so errors are only a small factor.
First test: Do a 30 laps race on R1 tyres.
Second test: Do a 30 laps race on R2 tyres.
In the first test the R1 tyres heat up to 80-85°C pretty quickly. They are orange-red. I achieve laptimes from 1:15:34 to 1:15:8* without counting unlucky laps (only one or two). No laptimes are counted where the tyres are below 80°C.
In the second test the R2 tyres heat up to 87° at the most, 82° at the least. They are in their optimum range. I achieve laptimes from 1:15:76 to 1:16:3* without counting unlucky laps.
(Most noticably the tyres lack the ability to put down power, sometimes understeer is a problem. The setup was adjusted to R2s.)
From a previous test I know that R1 tyres hold a good bit longer than 45 laps, which is over an hour race-distance. R2s will propably hold longer, but I didn't make a longer test.
So, what exactly is the advantage of R2 tyres? At the end of the 30-lap race I already achieved a 15 seconds-advantage with the R1s over the R2s. After 45 laps the advantage would be 22 seconds. Enough to justify twice as many pitstops as someone on R2s. So I assume that, at least for my driving, there is no condition where R2 tyres are useful.
My questions:
Was I just unlucky? Did other people make a different experience?
