object from blend to another(export/import/newbie)

How can I get object from blend to another plain wireframe object? and how can I get object with linked materials and textures from blend to another.

example. I have tire object in one blender file and body of bicycle in another
how can I get that tire imported in same blender file with body.

click “file”->“append” then choose your .blend file and it goes to the .blend directory, click object, then choose your object.

Once again Thanks
