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

Ok, I could drive down the road smooth as silk in the old 13 inch tires......change to 14s with new tires yesterday and the front tires wobble now--- not going over 15 miles per hour........feels like the lugs are loose to help describe it......can see front tires wobble a little and feel the car fighting to stop(though slight) at slow under 5 mph.....front right could use a ball joint....ok fine but left is good and sound........ideas?more questions for me to help describe?......balanced tires and undamaged rims....thx !
