I was a Big O customer before I moved to Seattle in 2001, so when I needed 4 new tires for my truck, it was natural to call them up. I got a great deal on those 4 tires and didn't really pay attention to the warranty and guarantees. Then I drove over a piece of concrete just after Thanksgiving and put a big hole in the sidewall. I was expecting to have to buy a new tire or at least pay for the repair. They gave me a free tire - there is a road hazard warranty. Great!
The store is always busy, so don't expect quick service, but everyone is courteous and patient. They recently had someone crash through their front window so it looks a little strange with plywood covering half the front of the store. Parking is difficult in their lot due to the volume they do, but they can count on me as a customer in the future.
