All I can say is that these guys saved my weekend.
We had a flat tire on I15 heading home to the LA area after 6pm on a Saturday night. Called roadside assistance who could help change the spare, but no help with tire repair/replacement since the dealerships are not open UNTIL MONDAY. In a panic I started calling local shops looking for a tire. Spoke to Gloria at Pep Boys and she not only confirmed that they stock the tire I need, she took my #, confirmed in inventory, and called me back - all while I'm waiting on the side of the freeway. She also confirmed that they would get the tire on my car THAT NIGHT.
Once we got there, we found both Gloria and Ricky very friendly and helpful. They ended up staying a bit late to get us taken care of - and at a price that was very reasonable.
I have never considered Pep Boys for tires before, but I will now. I can't speak to their other services, but I can highly recommend them for tire service.
