jeezuz...welll, i'm confused...very in-depth post, can you dumb it down for me, in layman's terms? Re "Even so, I would expect launch/longitudinal traction to not be substantially better on a 335 vs a 235 of the same tyre (if they existed). I would expect maybe some small difference, and that might be worthwhile, but it couldn't be night and day." in theory then given a dry day on a bitumen surface of reasonable quality, a 195 cheesecutter would have roughly equivalent grip to say a 265?
