2nd Gen Tire Size and Suspension Help

Hey guys, this is my first time posting here. Looking for some help. I have an 09 Taco, it used to have 265/70r16, currently runs 265/75r16. I bought some used wheels that are 32x11.5r15. I want to throw these new wheels on and am going to replace the tires on the 15in rims. Truck has about 162,000 miles, so i was thinking about overhauling the suspension anyways, possibly putting a small lift on the truck. I'm already hitting 11.5mpg with all the stuff I carry, so I don't want to lose much more. Other than that, I have no idea where to go from here. I'm not sure what parts to buy or tire size to run. Any help is greatly appreciated!

 

Most people report issues trying to fit 15” wheels. They rub the brake calipers

Also you get 11.5mpg?? What are you hauling?

 

Welp, that's a shame. Thank God I only got them for a $100 lol. Let's see if I can flip them.

I'm a construction superintendent. I have a drawer system I threw together that has my power tools, hand tools, and job files. Built it out of 2x12s and 3/4" Advantech. Probably way over built. Everything together weighs at least 500 lbs, if not more. I installed rear airbags as well
