I just bought these Cooper tires for my Explorer last spring and I have noticed that the outside of the tire is darker then the inside half of the tire. The outside is black like a normal tire and the inside half is like a light gray color! Is this tire browning or just junk tires? I hate the way it looks and no matter how I clean or dress it, it stays the same. Has anyone experienced this and does it go away? I normally use either Eagle tire & wheel cleaner or an APC to clean and Armor-All Original water based dressing to dress the tires. Below is a pic of one of the tires and this is with it dressed and you can still clearly see the color difference. thanks for the help
