Tire widths with coilovers?

[ATL SRT]

I will be purchasing some new vipers 20" vipers staggered (20x9 and 20x10) and dropping it with some KWV2s. I want to know what width tire I should go with on the front and rear to get a good drop without having to worry about rubbing. I was thinking 245 or 255 front with a 275/285/295 in the rear. I will more than likely be getting some Nitto Invos. Thanks for any information!

With a 10" wheel in the back, your going to rub unless you #1 roll the fenders up out of the way, which will allow you to adjust the coilovers to sit lower. Or #2 Adjust the coilovers so the fender sits high enough that it won't rub. I don't have the coilovers, but I do have the Sportlines which dropped my car 2 full inches. I have a 9.5" wheel with 265/35/22 tires and the fender would surely rub on the tire if it was 10" wide. As it is, the 9.5 gives me about 1/4" clearance. See pic. Hope this helps!
