Err.. nksc.. I think not even comparable lah... they're not even in the same category of tires.
When new, the RE-01R is grippy in all conditions.. even the wet, but with deep puddles more than 2-3cm deep can cause severe aquaplaning if at speed. (depends on your car's weight also lah.. A GTR probably wouldn't have it since it's so heavy.).. My car not so heavy soo....
The AD-07.. I used for a while, and never got a chance to use in rain. Traded in with someone else including the rims. However, everyone that I asked (in my group about the AD07 is always the poor grip in the wet.. it's not that it's not grippy, but you feel like it's not enough.. and doesn't 'inspire confidence' <- (B18CR SR3 owner, not me..)
For my current set of RE-01Rs...
As the threads start to wear, esp. around the sides.. traction is really starting to diminish... so much so that anything above 100kmh at sharp turns is a no no with the monsoon rain.. The loss of grip wasn't sudden... more like a feeling of understeering.. happened today when I overtake and forgot to slow down (slowly) for the next corner...
Probably have to bring out the 16" FTZs for this monsoon season.. they're not very grippy, but aquaplaning resistance is quite good due to it's deep grooves. And since it's constantly raining cats and dogs... probably a nice idea to hold on to the 215s until it clears next year. Since the rain = no play-play.. those FTZ tires also will have to do for now. :P
