There are a number of causes for vibrations. Use the "Search" button on this site, and start digging around. There's lots of threads on vibration topics.

 

Vibration at 60-70 mph is almost always wheel or tire issues. You can usually feel a lesser vibration at about 42 mph as well.

 

Your aftermarket tires/wheels prolly lost a weight.

 

Balancing is a big one like DZ said....Check the balancing on your tires.

 

Going to school? With spelling and grammer like that? Are you serious?
