How do I make it where it will show only one tire track instead of two. I have a bike model but it shows two tire tracks like if it was a humvee but it needs one track not two.
It's specified in the factionunit.ini entrys just below the units model information. The one used for the Humvee is EXTireTrack.tga. You'll probably find it in textures.big
Did you change the entry in factionunit.ini? Did you put the file in Art\Textures? Are you sure it saved properly? Other than that I don't know although it might have something to do with the locomotor.
