I would like to see more rim choice maybe 2-4 per car (as most real-life racing series use different rim manufacturers too), just like with the tyre brands. What I would like more than different sizes of tyres is still different compounds . Not the ones like R1, R2, ... but different R1-compounds, different R2-compounds, ..., which iirc Scawen already said would come sooner or later.
Some preset tyre choices could be interesting too (low profile wide tyre vs. higher profile narrower tyre), because we already learned, that wider doesn't neccessarily mean better.
Overall +0.75
