That is the factory size, but the problem is that since many companies (including Maxxis, and Yokohama) have stopped making them, tires that used to cost $50 each are now $125-$150 each. But the 70 series tires are more common and are still around $50 each from several manufacturers. I put lots of miles on my car and go through tires, many times thanks to Southern California's decaying roads.
