Car Vibrates above 80

[Eclipse IF]

Alright I got a question for all you guys, when I'm driving on the highway and I hit speed above 80 the car starts to vibrate pretty bad it still runs fine it just virbrates like a maha and gets really annoying! Is this normal? I don't think it is but I'm just checking. My dad said I could have a wheel off center that's cause it. Is this it? Or could it be something else? Thanks for any help you can give me.

It is most likely a bad tire(s) or an out of balance wheel.

For me, this was a bent wheel. It would balance on the machine and was actually okay below about 60-65. Once I got to 70-80, it drove me nuts!

bad tires here too. boy that sucked!

Check for a dent rim. I had a bent rim, and it would go crazy above 80.

You can also try getting your wheels aligned and balanced if you didnt do so yet.

hit any pot holes lately? you could have a "bubble" (simply a bad tire is what it sounds to me)...

tire deformation

Also check the wear in your rotors, and brakes.

Balance is the issue...

I had the same problem. Between 90 and 100 I would get bad vibrations. It stopped when I changed my tyres.
