Personally, I really think your situation is all a matter of luck. Talking about tire punctures reminds about something...the day before the Crossfire meet in August, it was about 10:00 am, and I was ready to wash my car. I point the hose at the right rear of the vehicle, and notice that the tire was FLAT!!!! I forget to tell you all this story, but to keep it short, I spent the whole day looking for a place to fix my leaking tire. I ended up paying $50 to have my tire repaired with an internal patch. Being inexperienced with this situation, I told the place that fixed my tire that I was in desperate need to get it fixed. With this in mind, I think they overcharged me for the service seeing that I seemed willing to pay any amount to get the tire fixed!
