Up until a few days ago, I had very little scrub noise from my original equipment tires. We had a cold snap (~28F outside, ~50F in garage) and I guess my tires have worn/aged enough that the treads are less flexible. Backing from the driveway onto the street now sounds like I'm driving over crushed glass or have a wheel bearing that is shot. I'm glad I only have to put up with it for a few days.
