Tires OEM BMW or BRIDGESTONE

Since they're now legal in my class I'll probably give them a try later this season after my current Bridgestone RE-71RSs are done

Blizzacks are the best.

I went from the stock Primacy to Bridgestone Potenza sports (300tw) and the difference in grip is absolutely noticeable and worth it.

I just replaced my stock Dunlop with Bridgestone Turanza 6 three days ago and they felt great.

For winter tires I'm using Bridgestone Blizzak WS90.

I have Bridgestone Blizzaks.

I got myself bridgestone blizzak lm005 winter tired, so far no complains.

I've been running them year-round on my 2009 S2000 since new - on Vancouver Island. Total no go in snow, didn't ever even consider of going on the highway, but backed out onto the driveway once when there was a couple inches of snow so I could move some stuff around in the garage. Only a slight incline, but it was not pretty getting back in. That said, we get lots of rain and they've worked well as long as there aren't serious puddles.

These tires are awful on my car. They're not performance tires by an means. They're meant to be driven and babied like a granny. In snow, you'd have to drive 30 km/hr or else it'll start sliding. In rain, it'll hydroplane after 90 km/hr. And in dry condition, it's adequate but loud on highways.

The factory Bridgestone tires only lasted about 24k miles.
