Tires Continental or OEM Porsche

Continental ExtremeContact Sport, 225/40/18

These are the tires this car should have come with from the factory. They are smoother, quieter, and (obviously) grippier than the OEM A/S tires in dry and wet conditions.

Got mine at America's Tire for 800. Best tires I ever owned!

The Michelin Pilot Sports A/S2 are the best tires you can buy for these besides Pirelli. I just put Continental DWS06 tires on my 2016 6 and it was like driving a different car. So much smoother and more responsive.

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.

I drive my 981.2 (718) Cayman in the winter around here in Ohio and it does fine with winter tires (does better than most AWD things with just all-seasons)

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.

The Continental ExtremeContact DWS I have on the car now, are pretty much worn out after about about 45,000 miles.
