Tires BRIDGESTONE or Kumho

Tyres: Kumho ecsta lx platinum

Personally I'm running Potenzas

Bridgestone Re71R for asphalt, BFG Rival 1.5 for concrete

Currently running Bridgestone RE760 Sports. Classified as "Ultra High Performance" I have found them to be a great summer tire on a DD.

I swapped my OEM tires for summer tires (Kumho Ecsta PS31), they provide much more grip and are a bit quieter though since they aren't LRR (Low Rolling Resistance) I do lose about 10% on range.

Absolute best grip in that size will be the Bridgestone Potenza RE71-R. That would be the 'autocross special' tire. It's a 200 treadwear rated tire, so it's legal in the SCCA Street classes, but it's very soft and extremely grippy.

Been using 225/45R-17 Bridgestone Blizzak WS80's...they have been great last 2 winters.

I have a set of 265/30/R18 Bridgestone RE71Rs I autocross them and daily drove them for a while. But pricey but worth it for performance. I've heard people refer to these as one step down from slicks

The OE tires (Kumho Solus KL21) still have probably 25% of the tread remaining, so they're not in need of replacement for that reason... even though they have become pretty noisy and have a bit of feathering around the edges.

my buddy just picked up ws70's for his 2011 wrx. yesterday we went for a ride up the mountains and both of us where dissapointed in the ws70's. There was no snow or ice, but we did hit wet/damp roads and the ws70's where very squirmy in the corners. they sort of understeer then snap and oversteer. I wouldnt suggest them if she does any sort of spirited driving.
