When going over about 65, there is a vibration in the steering wheel and the entire car seems to just shake. This is just cruising, not accelerating or anything.

So far i Have Gotten all four tires balanced, rotated and an alignment done.

What could be causing the car to vibrate? The Tires are pretty new, so i dont think it would be that... could it be something in my suspension?

Thanks!

I had fairly new tires on my car too but to come to find out one had a knot in it. That is what caused my shaking at high speeds.

I'm not sure this could be the case though, because I rotated the tires and there is still vibration in the steering wheel. Any other thoughts?

I have a slight vibration at higher speeds because of a slighty loose front tie-rod.

Definitely check the front end, check your tire pressures, and if both those things are OK, I'd rebalance the wheels/tires.

Could be a shifted belt in the tire as well, I was experiencing this problem not long ago, turns out my rotors were shot (got new brakes) and rotated my tires to get the shifted belt tire off the drive wheel.

I can still feel it however its not as bad.

I also rectified the problem with a purchase of 4 new tires. (incoming in 3 weeks)

it could also be a wheel bearing that is shot... Just check the front end and see what you can come up with

bent rim or wheels not being balanced right

Its only at highway speeds that it happens, but sometimes it goes away for a minute, and comes back.

Like I said, the tires were rotated, so i believe it may have something to do with the front end, not anything wheel/tire specific.

When Wheel Bearings are at the end of there life, dont they make a sort of moaning noise when turning?

How can I tell if my front tie rod is loose? Wouldnt this have been noticed when i got an alignment 2k miles ago?

A good alignment shop will check your front suspension BEFORE it does an alignment. So, I'll assume, for a moment, that you did go to a reputable place to get your front end aligned and before you got the tires balanced, they checked for things like a dented wheel. I just had my steering rack with the inner and outer tie rod ends replaced and did not have any vibration before that. I also just replaced my right wheel bearing because it was making a considrable amount of noise whenever I went towards the left. But a bad wheel bearing would not make the front end shake at speed. I've had relatively new tire with a belt that slipped(shifted) once and it did cause the front end to shake so I would go with that theory for now.
