Showing off the drop down hatch and back gun, you can sorta see the tires a bit better. Not a whole lot to them. Using follow me option and the line and circle tool its fairly easy to create one then copy it haver many more times you need to get a full set.

Also, sorry for the seemingly flat Dark Gray color, not really good with picking colors. Tends to be why i opt to just leave them white.

Modeled in Google Sketchup 7.

Enjoy~
