2015 Dodge Journey Problem, anybody know?

Okay, so I took it to be aligned. He aligned it and said it was barely out of align. but he took the tires off to check the balance, as he suspected that the most. he found both were terribly out of balance. I'm no tire balancing expert, but he said the passenger side inside was 1.6 out, and over 2 out on the outside. and close to the same figures for the driver's side. He balanced them and a smooth ride is here! hit 70mph to make sure. no more shimmy guys! maybe my tires will last now!
Thanks for all the comments, I love having a place to post problems and have nice folks help ya out. :)
