Although he looks dang good and feels like he could just plow through a building, I wouldn't exactly call the wheels low profile.
Very much something worth doing to Crosshairs... perhaps someone might even make Crosshairs some entirely new wheels and wheelarch covers. it might require a hing on the wheels to clear the leg pannels though and place the wheels on the back of the legs - which would be more accurate to the original character anyway.
If you did the modd to the MP IH and Ratchet, then you have their leftover front tires. Which these are from.
I have a construction like the hinges(ystem) on SIEGE Voyager Optimus Prime's front wheels in mind. Which modd?
