I lightly bumped the curb because this stupid lady was parked in the middle of the road.  I waited a few mins and noticed that she was not going to move.  So I decided to go around her and I did not see the curb was shaped funny (zig zag like pattern) so I nicked it.  When I got home I saw a crack in my tire.  =(  DAMN IT!  So I went to Discount Tire to check on the status of my tire.  I thought great, $$$ to replace it.  He nice rep checked it out and said I am good to go.  No problems, that part of the tire is there for the wheel protection and it did the job.   That is great he did not try to pressure sell me a new tire.
