I have a Jamis Allegro Sport Hybrid (6 months old) and has gone about 400 miles so far. Today I had an accident (in the UK) because the rear tyre got punctured after hitting a good size pothole. I took it to Evans Cycles (UK) and they did a quick repair job to fix the puncture. However, the repairman pointed out that the brake pads are burning the edge of my tyres and this is very strange to me. Is there any way I can use special brake pads so that I don't have this problem?
P.S. I use Shimano DuraAce 7700 style brake pads which are apparently very cheap.
Edit: From the comments and answers, this seems like the most relevant picture:
