No offense Del, but Kumho's are cheap for reason, they aren't great. I'm sure Korea is a fine place, but I don't want any tires made there.
Michelin makes a great tire, they're just expensive. If your not looking for a performance minded tire, the all season tires 94bmw was talking about are a good buy. But I figured if you own a Bimmer, you want a tire with a sporting nature about them. The Avon's I posted a link to are HP tires, not simply pizza cutters that will get you from point A to point B.
