2007 Acura TL Type S (47,800 miles) Yes, only 47k

SO I live in NY/ NJ area, with a crapload of potholes everywhere. About a year ago I purchased 4 brand new bridgestone potenza's and 4 new 18" ENKEI m52.

And last month i hit a huge pothole on the highway which damages my passenger side front rim. Almost immediately after i hit the pothole i noticed a strong vibration in the steering wheel. at high speeds 65mph +... I didnt have time to change the rim right away, so I had to drive around with it for a few weeks.

Today I had a new rim mounted and balanced. (Tires seem to be OK) While i was at it, i had all 4 balanced as well to make sure there were no issues. I assumed that a new rim would fix the vibration. right? Well not quite. I still notice a very slight vibration still between 65-75mph (obviously no where near as bad as it was), when i Hit about 80, dont really notice it as much?

My Question is, what other issue could be causing this vibration?
Wheel Alignment? (I dont realy notice the car pulling in any direction?)
Bad Balance Job?
Axle problems?

Again, it is a very slight vibration. But there shouldnt be any vibration at all, because prior to hitting that pothole, everything was running fine.

HELP! thanks guys!

 

You should try rotating the front wheels to the back to see if it makes any difference. If it does, then you know it's gotta do with the tire/s.

 

If you bent a rim, it is highly unlikely that tire isn't damaged.
