I got new tires about 2 weeks ago and the front two tires have since turned brown and they won't come clean. I've tried everything to clean them and they are still this disgusting brown color. The rear drive tires are still black no signs of browning. I haven't driven through mud, dirt, sand hasnt been sitting in sun.
They are BF Goodrich tires and its not just the sidewall but the tread too. Any ideas?
