So Guys welcome to my Tutorial ... First.. (Sry for my bad english) but i think you understand what i mean :) 

2nd .. My Tutorial is For adding other stuffs On GTA IV Import 3D Models from other sites or your own :) (I Used a Ramp that i Haved Downloaded for this Tutorial :) 
next step is Try to find an Object what you want there have not to many (Polygons) so its easyer (Under 10.000) ...I leave 3-4 links in description & here ...

now you have to make a folder with the name of the object what you want that you can find it later ... and now add the texture (.png.jpg. or .bmp) what you want for the object
into the same folder ...google it or use your own :)
(for me) for the ramp the ground, is a Rainbow Texture :)
