every time im on the highway doing about 70+ my car seems to vibrate..any one have an idea on what it could be? also my front drivers side tire has a bubble in it..could that be the cause of it?

Yep. High speed vibrations are likely to be related to balancing. I would have my tires re-balanced. The bubble definitely sounds suspicious.

If it's not the tire/rim (I really think so) then it would be the control arm or some other component... Good luck.

Have all 4 wheels balanced by a reputable shop... High speed balance.

does the car shake or the steering wheel?

It can also be from a bent wheel (or wheels). I've driven through a number of rough roads, and they sure do a beating on our wheels, as well as alignment. Also examine your tires for any bumps. Try these after trying to rebalance/rotate tires first.

no the steering wheel doesnt shake n the car doesnt pull..just my seats n radar detector vibrate pretty bad...its goin to the dealer on thursday so we'll see what they say

[BlackBimmer1991]

maybe its just the runflats then?

I'm pretty sure it's the bubble on your tire, www.e90post.com/forums/showthread.php?t=157293 you must have smoked a curb or something. There are steel wires inside of the tire that will get bent up on impact

If your tire has a "bubble" you should replace it before it blows on you at highway speed.

Your alignment could be off. Did you hit the curb before?
