2004 front end shimmy ??

[scottio]

OK....I swapped out my 20" wheels and tires for some 22". Ever since I did this , I occasionally get a shimmy through the steering wheel. It does not happen very much , and usually when I go over a bump, etc. Sometimes it will shimmy and sometimes it will not. So , it shimmies through the steering wheel and slowly just fades away. The wheels and tires were new, etc. Anyone else had this experience and what could it be ?
thanks

Something loose that is brought out by bumps

Not sure.....just wondering why it started when I changed to the 22's. Wheel/tire weight being heavier ???? Not sure .
