Definity Dakota AT2 would be good. They are a bargain version of the Cooper AT3.
The Definity brand is owned and made by Cooper.
I'd recommend either of those for great performance and good price. Of the two, the Cooper AT3 will cost a bit more, but might perform better/best. However, the Definity Dakota AT2 is a real performer for a bargain price tire.
Goodyear Silent Armor would be another great performer, but expensive.
Hankook ATM would be a great performer, except reputedly makes a bit more noise than the others I mentioned. It is expensive too.
Kumho Road Venture and Firestone Destination AT would be a good performers at a great prices.
