There arent many really working wheel covers for trucks, but I have ones which are best in user friendliness. If you like to help me with my companys US marketing efforts print few of these to your clovebox. Every time you see a stopped truck with trailer skirts and without wheelcovers give one press release to the driver.

This is not mandatory, but I would hugely appreciate it!
