wheel size

What is the biggest wheel size i can get for my 89' 240sx without mods..whats the biggest w/ lowprofile tires and without??

To fit any big tire/wheel with a decent offset your gonna need to Roll your fenders and since your rolling them pulling the rear fenders wouldnt be that much harder.

with a Roll/ slight Pull (rear) 18x8.5F 18x10
with 20mm Fronts and big pull 18x9F 18x11
