New Volks For My Sc400 Tire Issue Help Please

[Gotboost241]

Hey guys I'm new here And need some help from the sc pros...

I have a pearl white sc400 1992. I've always loved them when their done right and not cheesed up. Lol

anyways long story short I have bought some volk progressive ts wheels they are 20x9.5 In the front and 20x10.5 In the rear. I'd like to know if Amyone has done this before and what tire sizes I should go with I've tried a few sets I can't recall the sizes we tried. They either rubbed horribly or the stretch had a quarter on each side of the wheel showing (curb city). Suggestions welcome. Ease help me guys I'm dyin to gettem on and get my sc lookin right. Thanks again
