One most any AWD car the rolling diameter between front and back should be within 1%. This is where tire size calculators on the web come in handy. I’ve found a tire about 3 sizes wider, but 1 size smaller in ratio, generally meets this requirement. (245/35 and 275/30).
I believe the delta with the ZTK package is 0.8% with a 245/35 and 255/35.
