Yesterday, I noticed a nail in my tire. Not sure how long it's been in there, but the tire pressure seems to be fine. I called Discount Tire at 10am this morning and drove in at 11am. They removed the nail, patched/filled the tire and I was out of there in less than 30 mins. I was expecting them to force me to buy a set of rear tires (original tires since 2006), but no! He understood that shelling out $400+ under pressure was not ideal, and gave me time to think about replacing.
In conclusion, I will definitely come back here for a set of tires. Great customer service, nice people, and a comfortable environment. Thanks again!
