I'm currently running 265/75-16's on my factory chrome steel 16x6.5 wheels. What is the backspace and offset of these wheels?

I'd like to put 285/75-16's on the truck, but I do want to run wider wheels. I was thinking 8" wide. I was thinking I'd like aftermarket wheels, but I'm concerned about getting enough backspacing. There is also the option of running factory wheels from a newer truck, but I've read the 2000-2002 aluminum wheels are out of the question due to tie rod end rubbing and needing to machine the rear drums. Will the 2003+ wheels fit? Although, those are 17" wheels and I'm sure 17" tires are more expensive than 16" tires.

Any suggestions for an aftermarket wheel with enough backspace to keep the tires under the truck?

Thanks.

 

is there anybody...out there?
