Wider tyres will provide no real advantage*, and unless all the increased width is offset out you lose turning circle, nothing to write home about at the best of times, and if it is all offset out it increases the loading on wheel bearings and all steering components, and makes the steering heavier and with more kickback.
*Wider tyres will lower the effective roll centre, but given the lack of sway bars, this will not be noticeable in driving. The overall diameter of the tyre is the main determinant of offroad ability, and going to a larger diameter is definitely not a good idea with that engine. In soft going the tyre pressure is more important than the width, and how low you can safely go depends more on tyre construction than width. I will make no comment on appearance, as I consider it absolutely irrelevant in choosing tyre size.
