I ended up getting a set of Federal 595rs-rr. So far I'm pleasantly surprised, especially in the wet on the street. When new you can definitely lean on them as long as there is not too much standing water.
I would not put 235s on a 7J rim. The 225s I have now are already wide for the rim. I have a bit of experimenting to do With tyre pressures before I can say anything definitive about the grip though. After some initial trial and error I cut 2 Seconds off my previous best of 1.50. howevwe, I'm still not consistent enough to be able to tell what is Down to the tyres and what is me improving.
