So i just had my winter wheels/tires put on (Stock 03 wheels). When backing out of my driveway later i noticed a grinding noise from my front passenger tire. It happens at a certain point when turning the wheel. It is mostly when turning right and the wheel is at about 3 oclock. It sounds like a metal on metal grinding noise. My wheels were professionally mounted and this noise did not occur when i had on my Rota's. My initial thought is the issue of the rotor grinding that many Subaru's have. Any other suggestions for things to check out?
