With approx 5k miles on my Continental Extreme Contact DWS 06+ in 275/40/19 and 245/45/19, I thought I'd report back on how they feel/drive compared with the OEM sizes. This is my first experience with Conti's and I went with them based on the reviews for all season performance. To anybody considering this tire size upgrade... Do it! No rubbing, noticeably quieter and smoother than the P-Zero's, great handling and fills the wheel wells perfectly with a more "meaty" look. This size configuration should have been what came from the factory with this wheelset imho...highly recommend to anybody considering it.
