With a Terrain Tamer lift kit, would an 18" wheel/tire set fit?

There's a local FB marketplace seller with a set of BFG KO2 275/70/18 with about 1000 miles on the tires. Wheels are 6 lug x 5.5", and probably 6" backspacing. I'm assuming I'd be able to get spacers to fit. Just not sure how they'd look.

BTW, the seller noted that they were on his Nissan Titan XD.

This is what they look like. Thanks!

Comparing the other set of tires I'm considering, the 18s aren't that much bigger. Here's the tire size calculator. I'm assuming they'd fit fine, but I'm probably missing something in my thought process otherwise, I'd see more folks going with 17 or 18" wheels.

Fitment aside, going from a 16-inch wheel to an 18-inch wheel and tires of the same overall diameter means you'll lose a significant amount of sidewall height, which is not a good thing on a four-wheel-drive vehicle. Your ability to air down properly will be compromised, as will the ability of the tire to protect the rim from impact damage. You might even notice a reduction in ride quality. Installing wheel spacers will result in yet more compromises.
