Well,too start off,adding width does not add suspension travel....Second,and most importantly,is a terminology in suspension design known as "scrub radius"....In a simple translation,if you drew an imaginary line through your upper and lower balljoints,the line should hit the ground somewhere near the center of your tire......When it doesn't,small rutts or differences in terrain can rip the wheel out of your hands due to the feedback that gets passed through the steering wheel....It can be violent enough to break bones in your hands....Don't take my word for it though...Try it...Just be careful....
