1970 Dodge Dart Ttire Issue

i just today got my car back on the ground after installing the Southside Machine lift bars i have. it now sits alot lower in the back than it did before. i also now have very little clearance between the fender lip and my tires, about a half inch. the rims are "0" offset marked on the backside and are 15x8's. i'm thinking about folding or rolling the lips in and flat so they are nice and smooth, just in case the tire does contact them. i am worried later about wrinklewall slicks contacting the sharp edge if i just cut them back for clearance.
