You can look here for all tyre comparisions
also what Ph3nyz has said are good options.
Just remember when using the PIT SHUMIZU'S slicks they need to fix them to the TAMIYA FOAM rims which is detailed here,
the only Pit tyres that will fit on the RIDE rims are the grooved sets, they have a different internal diameter then the slicks
At the moment the R1 rear tyre works well in hotter conditions, I'd stay away from the fronts as they tend to push mid corner. if the temps get above what temps you have said then they will start to work better when worn in a little.
Also hit up the local F1 drivers for the right tyres, as they have done all the testing for you.
