Tires DUNLOP or Goodyear

Yes they are. I replaced mine with Sumintano HTRZ IIIs and things quieted down considerably.

I run Dunlop SP Sport Maxx and they are excellent in the rain.

Like Tim said above, it depends on the tire. Some are more dedicated to pure dry weather grip, some have a better rain compound and tread. Like poster #2 above, I have Goodyear F1's. The reason I chose those is because they are just about unbeatable in the rain, it's like driving on a dry road. They can stand the car on it's nose under braking, and grip harder when turning. They give up very little in dry ultimate grip, too.

It depends on the tire. My Eagle F1 GSD-3's are *awesome* in the rain.

yea, the Eagle GT's are what my mother has on her G35. Definitely resist hydroplaning well.

Great tire...Performs awesome in wet and dry conditions:

I really liked my Goodyear F1 All Seasons when I was living in Mass. They are an excellent combo for all weather conditions and performance.

Last year it was Dunlop Wintersport M3s, which were ok, but not as good as the Semperits

I am not happy with the quality of the Dunlop tires and I feel they should replace all the tires with a better reinforced sidewall in order to avoid the problem from resurfacing.

Having had bad experiences w/ a few different sets of Dunlop tires (most recently the craptastic SP Sport 5000s on my Genesis which are 90% worn with only approx. 10k miles on them since I run snow tires in the winter), I have to say I'm not a fan of their tires generally speaking.
