A few weeks ago, i got a flat tire driving through Carnegie. Luckily i was close to Knorrs, so pulled in. They were able to take me immediately, got two new tires, and they rotated them. I have some mobility issues, and they were so kind and concerned that I had no obstacles and did not fall. Had interaction with at least three of the employees, all were kind, friendly and professional. The car rides beautifully now, they did a great job!
