If Discount Tire will do it for free, then bring it there. Otherwise, I would repair it myself. Walmart sells the repair kit for $8.50. If you have a jack, you can repair it yourself in 20 (experienced) to 60 minutes (1st time doing it). I have plugged over 10 tires in the past 35 years (a few times, the tire store said it wasn't repairable because it was too close to the sidewall, but I did it and got another 20k to 30k miles on each of them). Don't replace the tire - that is a waste of money. By the way, I have 47k miles on my tires and rotated them only once at 44k miles due to the even wear. I believe that they will make it to 70k or more barring a screw or nail puncture.
