I knew about DT in Pittsburgh area, been there for a while now. I was unaware of the new AT stores in W-B and Scranton. Interesting they chose to go with the AT (vs DT) name, up till now mostly been used in the SW and West. But looking at the stores online, same design and color scheme as a brand-new DT store locally. Mostly white now as opposed to the traditional tan/beige with red of the past. I could see that area being easier to find more reasonably land locations for DT/AT stores. It's progress, slow but progress. Fwiw, after I posted I looked at the Milestar AW365 and thought that might be a good option to look at for the OP.
The Scranton/Wilkes stores only opened a few months ago. They use the AT name because Mavis was already using the name "Mavis Discount Tire" in the area, so they used the AT name instead.
