Swapped from Neova AD08R to Fleva, size 195/55/15 ... the sudden change in comfort is welcoming. But the handling, well, it's obvious when compared to the Neova considering I take most corners without braking. I have the AD08 on my STI for track, so the threshold grip I know it well.
Wet conditions under heavy rain, the Fleva performed remarkably great. Have not gone through deep puddles since I had it for the past week, so can't comment on hydroplaning. But it does give me great confidence when it rains heavily.
I've had 2 sets of S-Drive before, both times the sizes were 205/45/16 on my previous Jazz GE and the current Jazz GK, before I swapped to 15" Neova. Due to different profiles, I can't say whether S-Drive is more comfortable or not, but it does feel so.
I would say road noise is considerable lesser as compared to S-Drive, but the S-Drive had better grip that the Fleva at corners.
It's acceleration off the line is worse than the Neova, but that's to be expected. I find the tire flex a lot when corner, and I have to adjust my driving habit to suit.
Will feedback more after I run in more mileage on it.
Again, I stress that due to 205 vs 195 and 45 vs 55 profiles, it's an assessment that's not entirely accurate.
Yeah the comparison is not quite representative coz your previous S.Drive was wider and much thinner which can give the impression of much better response and grip. I'm surprised if the new Fleva is really not better than the outdated S.Drive, but if it's really is then this Fleva is not that good or comparatively much weaker than others of similar category. Good to know though that at least it's good in the wet.
