They are Cooper Super Road Master tires. Nice tires and as mentioned seem a bit bigger than my Firestones of the same size.
Getting bias tires up here is not easy. Most dealers won't even talk to you about them or give you some excuse that they can find 3 on the other side of the country. I got mine thru a specialty shop which imported them from the States. I did like the Coopers and would recommend them as well.
