(..there are similar problems on ATI too..!)
@ ArniV8:
I think the strange tyres in wet races come from wrong files/settings in GPxSet (->seasonset-> edit -> tyres->the Tread1,2 -files are very important, but I donĀ“t know why..)
and
you need HW+SW-jams(!!!) tyres with the exact(!!!) jam-IDs (best solution: go back to original GP3-files/config and modify again)
