I am trying to replace the tires but these rims have a special tool that
removes the plastic caps that cover the lugnuts. The tool looks like a "U"
with hooks on the end to grab the cap:
I don't know if that will display right, but it should give you an idea.
Does anyone know if I can buy this tool at an autosupply/tire store, or if I
have to get it from AT Italia?
