have used them for years and have been satisfied with the service. However, while replacing two tires on my recent visit, they stripped the stud on one of them. I found out the next day when my mechanic was unable to remove the tire. So to avoid having to pay my mechanic to replace the stud, i had to take it to one of Discount Tire's vendors, which was extremely inconvenient (time & distance). I now have to reschedule the original app't...three mornings out of my work week instead of the one originally planned. Discount Tire should have paid my mechanic to take care of the issue they caused.
