I had intended to replace the set I had with another set but the store in Warner Robins on Hwy 96 couldn’t get their act together and actually order in a set of four. I got only two and due to zero call back or willingness to answer a call to the store. I purchased a different brand and a different store. Sadly it’s clear Store Managers do influence culture at Discount Tire stores.
