So last night i get out of work at 9pm and i walk to the car and start it up to go home. I start to drive off and i am getting this thumping noise coming from one of the tires. So i stop thinking it is a flat, and i look at all four tires and they look great.
Then this mourning I took the tire off the front because i know that my brakes work making a little noise, and i thought a pad could have fallen and was rubbing, but i noticed this.

The asphalt/Tar must have melted on my tire while it was parked. It was around 90 the whole day so i could see it happen.
The tires were 2 months old, but i took it into Discount Tire and they replaced it with no problem.
