So with 150 miles my car is making a tick-tick sound when I'm driving along fence, building, etc. I recognize this sound from when my mother's car had a bolt stuck in the tire. Sure enough when I get home I find a big bolt head and 2 washers in between the thread blocks on the passenger rear. No air loss but as soon as I pull the bolt it hisses like a snake. I read the road hazard warranty info and it looks like they will give me a new tire for free. Does this sound right and has anyone had to do it?
