Nitto has a 37,38, and 40 with 3970lb load rating.
Toyo has a 40 at 4190lb rating, and a 37 at 3860lb.
Just depends how far you are willing to load or over load the rears... I know that a ton of toyotas and jeeps are well over gvw, but when the wet weights are in the mid to high teens, there are more serious concerns. That said...
Run it. 8k of rear axle weight is a lot anyway.
Questions about these wheels though.
What's the offset/backspacing on these? You had said that the cab and chassis is a different rear axle width from the pickup bed model. What will the track width difference e for each one?
What lug nuts will they be drilled for?
Any chance for a larger safety bead or ridges like the Method Bead Grip tech? Non beadlock wheels are nice, but it is nice to be able to air down as much as possible.
Thanks for doing the leg work o. These, hope it goes well for you.
Thanks Ross
