Tires sizes: 58x24, 62x22, 64x24 Body already slightly trimmed. Still rubbing of all sizes while fully articulated and from a certain steering angle. Rubbing get worse with tire size.
Stock is 56 mm when I remember right. As soon as you optimize the steering angle and use bigger tires you will have to trimm the body. Otherwise you will get rubbing on the body when the rig has to articulate and you steer. Using 64mm means quite a lot trimming.
