Stock tire size or are you going bigger? Ive run both KO2s and Duratracs. Currently have KO2's. Theyre heavier and your gas mileage will take a hit, but the ride quality is superior to the DTracs.
I got some Nitto Terra Grapplers from a stock TRD Pro I just took off - 4k miles on the tires. I can let them go for cheap. Tires are located at a shop in Highland Park NJ.
