Pretty easy. I don't have many issues with manual steering except when maneuvering into a parking spot and the like. The top photo is all 14", the middle photo is 14's on the front and 15's on the rear and the bottom is 15's on all 4 corners. Front tires are 165 80 15 and the rears are 235 70 15. The width of the tread has more to do with turning issues than the actual size.
