Hello,
I just joined the site because I am trying to get some answers to questions from people with much more car knowledge.
I recently purchased a 2009 G 6MT coupe and have had some vibration issues at the front end. I have had the tires balanced twice, and the second time the dealer stated the the balance was indeed off. Now the car rides better, but still a noticeable vibration at speeds greater than 65 MPH. is this a tire issue? the brakes are fine, the car tracks straight, this is my first set of low profile tires on 19" rims. maybe Its the way these cars ride! what should I do?

 

Try having them check alignment or for warped rotors.

 

You should try a Road Force Balance, it costs more, but it eliminates most of the tire vibrations.

 

Warped rotors only cause vibrations during braking, if his ride is vibrating on the move, it's either the balance is off, he has spacers on OR one of your wheels are slightly bent from hitting a curb or so.

 

If road force is too high it will vibrate. Madmax is right about a road force balance...

 

bought it new or used??

 

most likely tire balance.. but if u got it balanced twice already, might be problems with the tires itself. did you buy the wheels/tires used? if so, it might be due to the wear on the tires. i had this problem before too and it went away once i replaced my tires.
