My original Contis just got replaced at 32K and 3.5 years. I probably could have pushed them to 35K+, but the car was in for AP2 to 3 upgrade and the SC offered an alignment with install for $160 even though I had tires delivered to them for $570, Nexen N'Fera RU5 Korean tires someone recommended here on the forum for the MX. Only 200 miles on them, but so far I love them, no noise, gripped road during launch test, and no noticeable change in range.
