hey all,

I recently painted my calipers and rotated my tires at the same time (did the X pattern change). Now I am getting A LOT of road noise from them at speeds. The noise continues when the car is placed in neutral. The tire pressure sensor light has never come on at any point (ie. i assume they are inflated sufficiently).

The tires are Z-rated bridgestones on stock rims ('04 G35 sedan). I know tires get noisy after being driven on for some time (esp. Z-rated ones), but this seems only to have happened since the rotation.

Any suggestions as to why this is happening?

Here's something that might help, no one has rotated there tires using the
X method since radials came along. Put you tires/wheels back where they
were and see if this doesn't help. Bridgestone tires are going to be noisey
regardless, they're not even close to being good tires!

Check to see if you have directional tires. At some place on the side wall there is an arrow with the word "ROTATION". If this the case and you did the "X" pattern rotation, then your tires are rotating in the wrong direction. For directional tires the only rotation you can do is front to back.

It could be that they are directional tires and that I now have them in the wrong orientation - perhaps swapping them from right to left might solve this. Does this sound correct?

I work at a Toyota dealer(Technician), We dont do cross rotations because of this issue. Lots of times tires wear in a way (Most new cars are not camber adjustable without a kit) that this is unpreventable. Our recomendation or the way we do it is only front to back back to front rotation. As long as this is done every 5k miles you should have no issues. Sometimes the x does work but also might wanna make sure you dont have directional tires on the vehicle. if its so bad you cant live with it I say swap them back and use the front to back method and that might help with some of the noise. Also if you wanna get ccreative jack the PSI in all the tires to like max the tire allows and jump on the highway put like a a goour couple hours on them like that Ive seen that fix some real bad uneven wear issue mostly on new vehicles when they have tire issues from sittingon the lot parked to long. or if there not worth saving just pick up a new set and rotate every 5k. Hope my input helped.

thanks guys - I'll check tonight, swap them tomorrow, and let you know.
