Thanks Grigg;
That's kinda what I was thinking,I think the first step will be to try the bigger tires/wheels on the truck with my current spacers and see how it lines up. I think I have a pretty good space now,with the 9.00-20's on it,so hopefully there'll be room for 10.00's with plenty of clearance. I'm figuring if there's 2 inches at the widest part of the sidewall,I should be okay with max. load weight.
I'm guessing part of what you're talking about with the different types of clamps would be to compensate for the wheels being placed farther inboard or outboard from the base of the wheel studs;there's a couple of decent tire shops here,so if I have to change anything,shouldn't be too hard to find what I need.
Thanks again!
