The tundra nose tire is a Cheng Shin 15x6.00-6 (4-ply with
tube) on a Quad City 6" aluminum rim. This fork was custom made of
stainless steel pipe sized to accommodate the tire and set the airplane
in a slightly nose up attitude.
The wheel on the left is the standard sold with Challengers
in the United States for both nose and mains - 11x4.00-5 tires on lightweight
plastic 5" rims.
On all Challengers shipped to Canada since the fall of 2009
the standard nose is an oversize 6" fork along with a 6" aluminum
rim wearing a 13x5.00-6 tire.
