There is a good chance that your tire can be repaired if:
1. The tire has not been driven on when flat
2. The damage is only on the tread section of your tire
3. The puncture is less than 1/4 inch
Have an authorized tire dealer or mechanic remove the tire from the wheel and inspect the tire from the inside. This inspection is absolutely necessary because internal damage is not visible while the tire is mounted.
The proper way to have a tire repaired is to patch the tire from the inside. If you are offered a plug repair--refuse! Plug repairs do not involve taking the tire off the wheel for a proper inspection. A plug is simply inserted into the punctured area. Plug repairs are not reliable and can cause the tire to blowout. Insist on a full inspection and patch repair on the inside of the tire.
Hope this helps.......
Personally, I value my family's and friends' safety (and my own) to the extent that I just accept the cost of a new tire for a flat as an insignificent part of the operating cost of owning a Boxster;i.e. depreciation, insurance, maintenance, gas, etc.
