I'll never stop using Continental DWS06's if I have a choice. I've had Michelin, Pirelli, Khumo and plenty others and I'm just done. I drive my car season wide, so summer, monsoon, winter..... And no tire I've had on this car, compares even the slightest to the Conti DWS06's. Awesome Grip, very long life span..... Price is a lil ehh, Around 400 for my 285/35/19 rear's.... Each. but they are worth it.
A lil story on the lifespan.... I've had numerous alignments done. The Front tires for the past 3.5 Years have outlasted a set of Michelin, Pirelli and some Firestones. And I didn't even buy them new. They were take offs from someone that didn't like the size or something. I had issues with Traction or lifespan with all these rear tires. However the Front DWS's have outlasted and gripped better than them all. So I finally said screw it and put the most recent rear tires to the DWS06's. And still the front DWS's have life on them.
I absolutely love them.
