After researching tire reviews, the tires I decided on were carried only by Big O. They had four in their warehouse locally. Jeremy at the Tempe Big O was able to arrange for their delivery and installation within a day's time and at a convenient time of day for me. The cost was reasonable; I didn't have to wait long while they were installed. While I waited, I was able to use their Wi-Fi at the store, which helped me keep up with work . I will probably use Big O in the future. I do have a Costco membership, but Big O had the product I needed, and made it convenient and painless for me.
