As of today I have 15500 miles and I purchased the car October 2022.

Check your front and rear tires' tread depths. Since the Q4 is a rear bias-weight car, the rear tires tend to wear out more than the front ones. I recommend using a tire depth tread gauge to measure the tread depth of your tires. While the legal limit is 2/32 which is the height of the tread wear bars, it's advisable to replace the tires when the tread depth reaches 4/32 or less.

Btw, the Q4 tires are staggered i.e. the rear tires are wider than the fronts, so they can't be rotated.
