So, Im getting ready to put my new wheels on this spring and was in the garage trying to decide if I want to roll and add spacers. I felt under the rear fenders and the lip was parallel with the ground. When I felt the front, it is angled up at about 45°.
Is this how they shipped or did the previous owner roll the front?

 

Well turns out 18x8 +42 with 245s look good enough for me. Here's pics of new and old

 

The fronts have a slight bend/angle to them from factory. so to answer your question, No.

 

Roll it only if tires is hitting it
