I have had similar 60's out of both. My best with the 15's is a 1.65 and 17's a 1.66. The 17's are a good bit wider but lack the side wall of the 15's.

I hate changing them and wondered if anyone else thinks it's worth the effort? I must admit I have never had the 15's on what I would consider a sticky track yet.
