Switched to Dunlop Sport Maxx RT 2 on a 17 inch wheels from Dunlop Sport Maxx RT on 16.
Clearly the RT2 is a better tire, with lots of dry grip. Actually didnt push to the end still but the feeling is that the chassi of the car is no match for the grip the tires provide (bilsteins B12 kit installed). On the wet road the grip is again excellent as were with the previuos gen. RT. Very impressed by the resistence of aquaplaning as i drove in a hell of a rain and the contact with the road was lost between sbove 95 km/h. Progressivness is good but i still have not reached the maximum of the tire so will comment on how the tire perform when pushed to the edge later.
As the previous gen. RT was so poor with the wear i hope that this one last longer and acctually there is hope for that as the Treadwear rating is 300. The initial depth of the tread is 7.5 mm. (tire weights 9.1 kg.)
Comfort is good but not perfect. As for the ride comfort of corse going from 16 to 17 make a difference and you start to feel all the imperfections of the road (given the sport suspension take its toll too). The tires are rated 69 db. and on a good road pave they are really quiet, but once they hit bad passages with rough pavement the noise becoumes pretty annoying.
On the fuel economy RT2 performance is down in omparisson wirh RT as the rolling resistance is worst but that is expected from a UHP tire.
