Tires BRIDGESTONE or Kumho

This has been my tire choice for auto cross and it’s done amazingly well. Good feedback, good grip, stiff enough even for camber limited cars.

My two complaints is its longevity is not great but it’s a sprinter style tire. It’s not meant for endurance. And honestly, my biggest gripe is the cost.

The Blizzak 6 is closer to the Blizzak LM001 series. Better wet and dry handling, for performance cars vs SUVs and trucks going in deep snow.

Lots of good info on here and from looking at the tire, I think they made a big improvement getting rid of the rib near the outside shoulder and moving all of them in board. My 71RS has shown wear on the outside edge and the outside edge of that outboard rib. This should help mitigate some of that and get a stronger contact patch in the corners.

The Kumho's are a 200tw track focused tire that can be run on the street. The limit of grip exceeds anything the PS4S can do, I'm sure you can push the V730s to the point were you can get he tail to slide but it is going to be at a much higher speed and a harder to control.

Mine is a 2018 VA WRX base, I have Blizzaks, WS90 model and they're excellent in deep snow or ice.

I got 360k on an axle of Bridgestone Ecopia and 300K on the other axle.

My R came from the factory with the Bridgestone Potenza S005s. They're decent for daily driving—good grip in the dry and pretty quiet—but they’re not amazing in the wet.

Bridgestone - from a handling perspective they are great - from a road noise perspective - they are a bit loud. I won't buy them again, but I'm certainly not throwing them away.

For reference, crappy and expensive Bridgestone Alenzas (summer tires) were put on mine (21 inch)

For whatever reason my Bridgestone tires always lasted half of their warranty if that, and generally sucked all around.
