Tyre recommendations?

I havent had a lot of experience with various performance tyres as once I have found a tyre I like to generally stick to them.

The best all-rounder tyre I have had so far are the Dunlop SP Sport Maxx TT's. They have decent dry weather performance and have outstanding wet weather performance. Though at first I was disappointed with how they handled in the dry as I came from having Falken Semi-slicks on it before hand. But you get use to it quite quickly and you realise how capable the tyre really is. As for road noise they can be considered noisy but compared to a semi-slick they arent at all (If I get tired of listening to it....I just wind the windows up). They dont seem to wear out too quickly either; I got about 30-35k (rear tyres) out of them.

Im trying out the Sport Maxx GT's at the moment and can honestly say they are better again. They are similar to the TT's but with more dry weather performance and close the gap between a performance tyre and a semi-slick. Time will tell how quickly the GT's will wear but from what I have heard/read, they apparently wear quicker than the TT's and can expect to get about 20-25k (rear tyres) out of them. 

On the front i'm running a 215/35/18 and on the rear a 235/40/18

Can't go past Hankook ventus sport V12's for all round performance, wear and price. I've had them on my past 3 cars and would buy them over and over again. They're between $270-300 a corner, reign in my SW20, V35 and 944 without any problems, and on the V35 had done 35,000km, still well above the wear markers and good for at least another 10,000km. Compared with Bridgestone Potenza they're almost silent and much more grip, wet and dry.

Anyone else running the Federal 595 RS-Rs? if so how much you guys pay for 215/40/17s
thinking about getting another set for the front :)

I'm running RSR's and am very impressed. I came from stock 15' wheels with T1R's. I paid somewhere in the realm of $1,000 fitted for 215/40/17 & 235/40/17 but can't remember if this included postage from QLD.

I also use the RSRs on my AW11 and they handle putting the power down well in the dry. In the wet, well its wet so I take it easy and its not a problem. Too much gas will get them spinning easily.
 
I think they probably are a bit noisy but its hard to tell in an old rattly AW11 :) 
 
On my wife's Mercedes it has Continental Contisport contact tyres fitted and they are very quiet and very grippy wet and dry.
