I decided to stick with the 265/70r18 Toyo AT3 (same that is on the Trailhunter Taco and the GX) as the tire shop wasn’t sure about 275s clearing at full turn (slightly taller and wider than 265s). I imagine they’ll fit but as I don’t have the truck to measure, I opted to order the factory size.
GX Overtrail looks pretty good with these tires so I got them in a 10ply rather than of a 4ply for increased load capacity and sidewall protection. I think there was a 5lb difference between the plys (43lbs v 48lbs). KO2s were a little over 50lbs for the 10ply.
I’ll run these for the first set and maybe plus up to a 275 or 285 next go round when there is more info on fitment.
