Quick question: I just put a set of 17" type S wheels (with brand new Falkken ZE-512 tires) on my 00 TL. I'm noticing a subtle and anoying vibration when I'm doing +65 mph. Can this be attributed to a bad wheel alignment/balancing job or does putting these 17" type S wheels on a 00 TL cause this?

 

Bad balancing job.

 

I've purchased 4 rims and tires from Tires.com and they balanced and road force. I also have a vibration at about 65+mph. Than again, I have 215/50/17 mounted on a 8 inch width rim.

 

This sounds to be a classic output of the wheels being ont of center of gravity or it has a bad balance. Get it re balanced and see if it fixes the issue. Some times if the wheel is bent badly, you will never get the wheel balanced..
