1-2 inches

It "IS" a truck which gets used off road, so I can't "slam it", and by raising, I'm talking 1-2 inches, not the stupid "How high can I go" BS. I have found some load range "D" tires which are about 1 1/2 inches larger dia., that will help the gearing some too. They are rated to 65 psi, so 45-50 would be good I think. No wheelchairs here, I've got 40+ years of 4-wheeling, and have only rolled once (off road race long ago)! But thanks for the concern! Your Toy was probably a 4 cyl with 33 inch or larger tires, they don't like those without major gearing changes. I have no power problem, 4.7L. I-force, V-8, so It'll pull 33 inch tires easily. Plus with the higher load rated tires, they get taller without getting a lot wider. I'm not looking for "The look".
A couple inches will expose a slice of tire on each side and maybe a bit more of the naughty bits underneath,so it doesn't sound like a monumental departure from where you're at.
Your daily requirements will dictate your needs,and it sounds like the clearance would be welcome.
I hope that's not fast-moving water that you've got to go through.
If you can post a few views of the truck it would give us something to 'think' about.
And yes,the p'up out here is a Toy,with the 22 or 24-R.Don't recall.I think it's 31-inch tires on that one.It will have similar needs.
