Michelin LTX A/T 2
I've always had good luck with Michelin's, but they tend to be kind of expensive. They make up for it by being long-wearing and smooth running.
I've got a set of LTX M/S's on my old Chevy pickup, but they don't come in a size that fits the Tundra. However, the link above for the LTX AT2 sounds interesting. Also, you can get them in load range E, which provides an extra margin of safety.
