N California, they are America’s Tire. In Arizona, they were Discount Tire Co. They have me in their database, had good tire options in stock, and were really pleasant and helpful. Both times, I could not have been in a more foul mood (especially the second time which cost me a money making day on the road), but they made fixing the problem easy. Definitely recommend.
Of note, I called Discount Tire Center here first, thinking they were the same company, and they guy on the phone was dopey as hell. They get a full non-endorsement. And fuck Les Schwab and their tread cutting scam.
