look to see where it's rubbing. When I had 225/50-16's, it looked like the fronts occationally rubbed the struts. While under the car, I could see it was pretty close... even at rest. I'm pretty sure mine only rubbed due to sidewall flex -- going fast through turns.
You might just need more air... please tell me you don't only have ~32psi.
Also, this thread will probably be moved to Wheel/tires.
