I can not get my MP3 through an emissions test because the tires are to low profile (205/40/17). They (in colorado) are telling me that the tires are to low of profile, so if they put the car on the strap (whatever that means) it will bounce back and forth on the stand an F up the wheels. Anyone ever heard of this, it sounds kind of odd, but at the same time I don't want to mess up my rims even though they are F'ed up all ready.
