Tires BRIDGESTONE or OEM Subaru

Blizzaks have been great

Almost 10 years in the tire game and my favorite tire is the Bridgestone Blizzak. Performs great in the deep snow, very well on ice and wears well and are affordable.

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.

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.

Had the Conti All Seasons last winter and was not real happy how they performed on ice/snow. Wife was slipping and sliding all over, especially in single digit temps. Took advantage of a Costco Bridgestone deal and got the Blizzak snow tires for about $700 after installation. Haven't had a chance to test them yet in the elements, but the ride is very quiet although a little more floaty/soft. Can't take the corners as fast as you would with the Conti's.

I have had a few sets of blizzacks, and while they were great on slick roads, I found they were not good going through a few inches or more of snow and were terribly "mushy".
