I have an autocross to attend this weekend and I have a decision to make involving what wheel/tire combo to run. My car is a G3 Integra in ST class. I have 2 sets of wheels/tires to choose from:
OEM 15x6 wheels with 195/55/15 Dunlop Star Spec tires, or
16x7 Slipstreams with 205/45/16 Yokohama S Drive tires.
I guess I cant decided between wider wheels/tires, or smaller wheels with stickier rubber.

 

The dunlops will be faster...

 

Thats what I am thinking.

 

Dunlops will definitely be faster, 2 different classes of tire.

Compound > Width

 

+1

 

another for the dunlops....

 

Not only is the dunlops going to be quicker and sticker, your going to have better gearing.

 

Race the Dunlops and daily drive the S drives

 

Not true. If you're referring to the difference in effective gearing due to the difference in outer diameter, the 195/55-15 is slightly larger, so the gearing means slightly worse acceleration. However, the difference in diameter is less than 1 percent, so you're talking about an infinitesimal difference, so it really doesn't matter.

 

Another vote for Dunlops. Totally different tire than the S Drives.
