I have been very happy with the performance of these tires over their 39,000 mile life and will probably replace them with another set of Spec-X's. I was hoping to get more than 39K out of these tires since I do mostly highway driving (commute 95 miles round trip for work), so I am somewhat disappointed with the tread life. On the other hand, the tires really improved the handling of my CX-9. Performance on dry pavement is superior and cornering stability is awesome. Traction in the wet wintery mix that is common in the Washington DC area is very good. When the tires were new they got me home safely during a bad snow storm that left many motorists stranded. The only performance issue I have with the tires is hydroplaning at highway speeds during very heavy rain. Maybe it's just the size of the tire (20), but I am more cautious driving under these circumstances. If tread life isn't as important to you as performance, then definitely buy these tires.
