Finally, Round Tires

I have no idea why the merging on the tire was not working, I just kept trying different settings and it finally worked. Sometimes Blender acts up in insane ways, but I have learned that if you "apply scale and rotation to objdata" (control a) it can go a long way solving these issues.

Thanks to Blender Cookie for the tip!

Tires don't have hubcaps yet, and they are merging strangely. The Blender curve array tools can behave very strangely sometimes.
