Need help in wheel vibration

[george1202]

I have an 03 3.0 with 19 inch Y spoke wheels and I'm experiencing vibrations on speeds of 60 to 70 mph. I already brought it to a shop with the Hunter GSP9700 and it imporved a bit but still with vibration. They said tire wear was evident. I measure tread depth in the middle treads and using a penny, it still covered Lincoln's hair and forehead. The side treads however showed the top of Lincoln's hair. I have the following questions as a newbie:
1) Do you guys think I need to replace my Michelin's?
2) Will an alignment solve this vibration issue?
3) Does anybody have the alignment specs for an 03 E53?
Thanks
