Yup. If I wasn't so concerned about having additional spares, I'd probably just leave the 27"s on there. But, Big Bend State Park and super remote areas in Utah that I'll be traveling typically it's a good idea to have more than the 1 spare on the truck. Having another I can take from the trailer (even if I have to abandon the trailer and return with a replacement) seems to be a good idea.Which is why the 27 will give a smoother ride too.
I figure I'll run about 22psi on the tires when loaded. They are e-Rated like the tires on my LX which are stiff (KO2). I run 42psi front and 46psi rear on my LX which is right around 7900lbs in full overland mode. 38psi front/40psi rear when daily driving.
