So I have read the looong 2.5 tire thread and may have missed my answer (if so, I apologize), but I thought I'd throw this out there. I just took a new position that will require about a 115 mile round-trip commute until we move (which probably won't be for 6-8 months). Since I love driving the Roadster (and it is the most economical car we own to drive) I plan to continue using it as my daily driver the majority of the time. That means 95% of my next 15,000 to 20,000 miles will be on the interstate at 70mph (or so). I am willing to sacrifice some performance for comfort and noise reduction. Anyone have recommendations of what they have/are using and like, or tried and didn't like? Btw I have a 2.5 so tire learning shouldn't be an issue. Thanks.
