Bent wheel, or worn suspension parts. I'm guessing it is the cv joints and/or stabilizer bar

While I own a Chevy Lumina , I haven't had this particular thing happen to it, However I have had it happen in domestic and foreign before. there are many things that can cause your vehicle to shake.

Tire Balance: Did you have them balanced when you had them replaced? Some companies now charge extra.

CV Joints a broken CV joint will cause the tire to "wobble" Most of the time there will be a distinct clicking as you are turning coners..but by no means is that a rule.

)if you suspect it to be a CV joint, get it to a mechanic pronto, not fixing a CV can lead to many more repairs such as a half axle or a whole new axle.) How is the suspension of your vehicle? Are your shocks/struts in good shape?

I hope that helps! Good luck on your car!
