: Vibration From Front End

12-18-06, 10:14 AM
Hey guys....I have an 06 STS AWD 1SG with 20,000 miles on it. I have been reading about the tires not having to be rotated. Recently i have been noticing a vibration that gets worse as my speed increases and the opposite obviously when i am slowing down. it seems to only happen when the tires are cold or at 30 PSI. Could this be a result of the tires not being rotated??? Is it possible I will need new tires at 20,000 without a rotation??? I would appreciate any advice you all have! :-)

If it happens at cold temps, its likely due to flat spotting. Does it go away after you've been driving for a while?

Yeah it does go away after a while. But, it happens pretty much every morning when the tires are cold.

Take them in and have them BALANCED if you cannot rotate.
