What is the biggest Nitto Ridge Grappler that can fit on stock 18s with stock suspension?

285/70r18 no problem, I am betting 295/70r18 ridge grapplers would be good too. Its only .3" bigger

Those look great! Do you know if that tire size fits stock 18 rims and stock suspension?

I have the same truck without any air suspension

I do not know, sorry. I did the rims, tires and level kit (Motofab with new UCAs) all at the same time. No air suspension, just stock plus level kit.
