Tires OEM BMW or Continental

I'm running Continental PureContact LS 195/55R-16. Massive improvement in wet and dry grip over the stock Hankook.

Continental Viking Contact 7 on VW wheels. They are great snow tires, quiet on dry roads but very effective on ice and snow.

For the Pacific NW USA, where it rains a lot, I keep coming back to Continental CrossContacts. Tire Rack ranked them highly for rain (my #1 priority) and very high just about every other category.

The Continental is the best there all round and would be my choice.

For stock suspension and even lowered 15mm on coilovers, I have really enjoyed my DWS06+ 235/45/18’s. They ride great, handle better than any all season tire I’ve ever run, and have smashed some serious potholes on the rare occasion that I can’t avoid them.

Continental makes great tires. My favorite tires are Continental DWS 06+. I've ran them on 3 cars and will continue doing so indefinitely.

I’ve left extreme contact sport tires on my car down to about 25F a few times. No flat spots. I’ve driven in 33-35F and they definitely had way less grip, but I was careful and it was fine.

Lots of people have mentioned gp5k, which are very fast, but continental also sells "all seasons" tires which are kind of best of both worlds between gp5k and gatorskin. Not quite as fast as 5k, not quite as much protection as gatorskin, but very close on both counts.

Now with 17K miles i have had three flats due to the well known issues with Stock Conti's on the 20' Rosarios. Replaced with Goodyear upfront and so far so good.

They are awful in snow. So I only run them for 6 months, and Continental Viking Contact 7 winter tires for the other 6 months. 8000 miles on each and only a little wear.
