Does Tire Repair Require Alignment?

[TVC15]

Thanks for the lively discussion. I have never patched a tire before, for the reasons you mention. However this time there were a few mitigating circumstances:
1. the tire has only 3500 miles on it, it was a simple puncture from debris.
2. the dealers were no help--they said they don't sell tires and refered me to a high performance tire shop.
3. The shop told me the tires were a new model and would take a while to find and get (i guess porsche modified the standard Continental tires for the 987 and they are not widely available).
4. My driving is city driving, with very rare instances of reaching 75 on the congested LA freeways.

That being said, perhaps i should have the shop find the tire and replace it. Another question:
given the low mileage, can i get away with replacing only the one, or do i need to replace the other front tire as well.
What procedure needs to be performed once the new tires are on?

Thanks
