I bought the Yokohama Geolandar A/T Plus I
tires for my '97 4runner
So far I love them, they're a bit more agressive than I had wanted initially, but they're wearing pretty good at 1000 miles.
I took them in some nice deep mud when I was last at the race track and they worked flawlessly. Scared the jeep owner I had in the truck with me, he didn't think we'd make it, but the 4runner with the yokos just pulled right through.
Suprisingly, gas mileage has not suffered at all, I'm running 20-22 mpg on mixed highway/city driving at cruising speeds up to 80mph.
They're also excellent handling (for a truck tire)
