Yeah, that's exactly what I was thinking. The used slicks cost less than a brand new set of 200 TW tires that I would normally run. I should probably think about buying a 3rd set of wheels to mount the slicks on, so I have 3 sets of tires to choose from depending on the weather. I just need to figure out what set of wheels to try and find in a 17" rim size...
The 2 options right now are Dunlop Direzza V2 Star Spec that are at about 50-60% on 17x8 OZ Superleggeras.
The other option is Bridgestone RE-71Rs that are ~95% on 17x8 OZ Superleggeras. I guess you could say I like the OZ Superleggeras.
Sorry, I couldn't help myself, but add a couple of pictures.
