Last tires I bought for my Silverado were Toyo Open Country, excellent tire...I've put around 50,000 kmtrs on them so far, tread shows very little wear, and the tires improved my fuel mileage slightly. The tread is more of a highway tread, they are quiet and return better mileage than my previous Firestones(were also good, put 125km on them). They actually have good directional stability due to the two deep channels in the tread, but they do lack on the traction side as they are not particularily aggressive.
Sorry, I'm not familiar with either of the companies you mentioned, Michael, but make sure you do your homework if they're "offshore".
