I'm always tempted by the non-premium brands because they stack up well in the tests against the big names and yet are much cheaper.
I had the hankook v12 evo's on my old 205 GTi in 195/50/15 when I sold it. Really liked them, melted a bit on track but very consistent handling on the road. Strange that folk say they work really well in wet, because I felt that was their weakness. For perspective, before this tyre I ran Toyo T1R on the 205 (which lasted 8k miles) and the V12 was significantly better in the dry and no real difference in the wet, in my opinion. If you search for "auto zeitung tyre test" you will see that the german mags really rate this tyre as an alrounder but EVO, who put more emphasis on the subjective, rate it low down against the premium conti/michelin/bridgestone... and, yep, Uniroyal rainsport2's!
I had the Khumo KU39's predecessor, the KU31 fitted to an MGZS180 a few years back as I had read good reviews of the Khumo's top performance tyre. It dulled everything down and although it gripped consistently it had no edge to the steering and was a big step down from the Michelin (PE2) and Bridgestones (RE050a) that I had before... It made me think that the big names do give sharper dry dynamics whilst still giving acceptable wet grip. To back this up, from what I hear of the newer KU39 it has little to recommend it over the Hankook, and down on the big names.
In my opinion, depending on the size you need, for normal hooning around I would go for these (in order of budget):
205/45/16
Dunlop SportMaxx TT (about £100-105 fully-fitted) --- NOTE THIS IS THE TT VARIENT.
Pirreli PZero (about £90-£95 fully-fitted)
Hankook k110 v12 evo (about £80-85 fully-fitted)
195/45/16:
Continental ContiSport 3 (about £80-£85 fully-fitted)
Uniroyal Rainsport2 (about £70-£75 fully-fitted)
I don't think it is worth going for Michelins' PS3 (I have, PE2 on front and PS3 on rear of my 182) as they are costing serious money now. If ultimate dry grip for fast-road is important I would go for Yokohama AD08 in 205/45/16 (about £120 fitted) and if trackdays then 195/50/16 Toyo R888. IMO
