Just went to Duke's over my lunch break from work to have my back drivers side tire patched. I work on the South side and try to take care of as many of this type of problem as possible over my lunch break. That being the case, I couldn't be more happy with their service. No appointment necessary and my tire was patched in less than 10 minutes, plus it only cost $15. I'm going to go here for all of my tire services in the future! For what it's worth, I have a 2012 Mazda 3.
Great service and took no time at all!!
