Help - vibrations from front end on new 14s not there with the 13s on

took left front wheel off and put on one of the old 13s ..I do feel the wiggle on all four tires one of the previous posters mentioned but the left front wheel or tire is the problem for sure....ran gloves over the tire and treads and looked it over and tire looks and feel fine---rim looks perfect too....one of you mentioned perhaps the lugs need to be ground off a little...will look into that too now....will simply add an additional washer to reduce the depth .....wheel weights not rubbing on anything.....was able to get up to 45 mph in town with no other big problems.....will talk to the tire store though and mention to them perhaps this style car needs a different tire type to not wiggle like a poster mentioned...the wiggle isn't a problem but under 10 mph I do notice what he said...
