I didn't notice this after I upgraded my tires to RFP1 17/18 (215-40 front and 275-35 rear), but now, when I backup, 8 out of 10 time, at the intial backing up, I can hear a very low and short rubbing/griding sound, and it goes away as I increase speed. As I stop to hear the noise, as long as I am very slow, chances are I might get to hear it again after 1 or 2 revolutions of the wheels. I am positive it is not the tire rubbing against the wheel wall, as I can see a hugh space between the top of the tire and my fender line. (I had someone jokingly saying my car looks like a 4X4 because of the clearance). Any ideas?
 
Is the noise coming from the front or rear. I have heard grinding noise from the front last time and it was my fender liners that rolled back on the tires after the fasterners broke at high speed.

I am not exactly sure, because it is very low, and quick. I believe though it is from the rear.
 
When all my pads were shot at 48k km I drove another 200-300km at least and then the car started making a horrible noise in the rear when reversing. New pads fixed it.
