I have a 94 Nissan Pathy and am trying to figure out what size tires I can get under it.  I am looking at cranking up the torsion bars and new coils in the back.  Also I am going to cut the fenders, but after a few inches I will start interfering with the doors.  I am wondering is how far I can go with the torsion bars before the upper ball joints are tweaked out to far?  And could anyone give me a rough guess at the tire size I could fit?  Also of course the truck needs to stay a daily driver HAHAHA. Thanks.  

you can probably get up ta 33 inch tire if u make some suspension mods and crank the torsions...wouldnt go any higher then that  

What is the best way to determine what size tires I can fit without actually having the tires?
