Time to replace the summer tires on my wife's van. She drives about 6K miles a year, which about a third of that is on snow tires here in Utah. Considering she only puts about 4k miles a year on the summer tires, would it really be worth dropping the money on name brand tires vs. the Discount Tire brand, Arizonian? Appears they are made by Cooper Tires.

Depends on the generic brand and the name brand.
Arizonian is a good house brand tire. Goodyear is a sh*tty name brand tire.

I wouldn't hesitate on Arizonians.

Arizonian is a very good tire.

DT also carries tires made for DT such as the YK580.
