Slicks 210/575/15 vs 200/580/15(190/57/15)

Hi guys,need some r15 full slicks for my ClioSport 2,with tuned engine(cca195ps) and suspension. Im thinking about federal fz-101,but its just in 210/575/15 which is not standard width for this car.I can have them for good price.What do you mean, use this slick parameter or use 190/57/15,200/58/15?

Cheaper option is standard semi-slick federal fz-201 with tw40, I dont know if its just cutted slick from 101 or its different compound. Thanks.

What width wheels do you use? 210/575/15 is wide, you'll need a 9" rim
Most use a 180/58 on a 7" rim.

Here's a picture of my 200/58 on 8" rims.

@Mirec8684 and @scruffydubber Out of interested assuming your running slicks on a full track car?
What spring rates are you using?
