Tires Continental or MRF

Not on your list but the best all season is the continental dws.

Well balanced and smooth at any speed. Tires are in great shape with almost new thread depth.

I have a set of the new Continental extremecontact sport ready to throw on very soon. These tires were designed to compete with the new Michelin summer tires. Tirerack did a performance test on the top summer tires and they performed just under the new Michelin PS4S but for way cheaper.

Most people conclude that Grand Prix are the best mix of puncture resistance, weight, grip and speed to sort of be the industry standard.

I can recommend continental, Pirelli or Dunlop. They all are pretty expensive but it's worth it, considering how much better they drive on e.g. a wet road or something. have a look at tests, continental is usually #1 or #2, that says pretty much about their quality. I personally only buy Conti and have never been disappointed, my dad has kumho on his car and they are so slippery it's scary.

Have you looked into the Continental ExtremeContact DWS? Discount Tire Direct's eBay account has a sale right now $100 off of $400 with free shipping.

I had my Conti DWS tires installed today. I’ve had them on two previous cars and they’re my pretty phenomenal across a broad range of conditions.

I ran the Continental Extreme DWS on my last M3 year round here in Colorado. They did really well in the summer mountain drives and served me just fine in the snow.

They did fine, not a great performing tire but for the price they aren't bad at all.

My biggest gripe was that you can't tell how much life it has left in the rear, since it had a smooth center. I just noticed mine showed cords one day.

Stock Contis are history at 30K The roaring inside the cabin due to cupping has become unbearable, so I wear foam earplugs and my shooting muffs over them.
