could be a loose lug nut.

could be a loose lug nut.

I just had the tires rotated and still have the vibration, tires are brand new.

How bad is the vibration? I had a bit of vibration last winter after installing my new winter tires but after a few weeks it went away.

arnt balanced properly?

Most likely, one or more of your tires is not balanced properly, take it in and have the tires checked/rebalanced.

i had the exact same thing, when my new tires were put on, someone crushed the hubcentric rings, and didnt notice it. so when i drove faster, the steering wheel and car vibrated, and i was like wtf. took me a while to figure it out. cost me 10$ fix or in my friends case, the tire was damaged on the inside, the belt was broken. whole tire replaced. either that or lose lugs/balancing which ami and ryan stated.

I'm experiencing this too. I haven't been driving my 3 as of lately because I now drive a company vehicle. Anyway, last month I had brand new tires installed and yesterday while on the highway, noticed a faint vibration at about 90km/h. Taking her in later this evening... Oh, and I'm still waiting to receive my tire rebate in the mail from Dunlop! :complain
