I can't tell from the pics -- is that 2wd or 4wd? If 4wd, don't mismatch the front and rear tires. Even for a 2wd, I don't like the look of mismatched tire sizes.

The rear is easy to lift. Buy a set of longer u-bolts, and install a two-inch block between the axle and the spring. https://www.offroaddesign.com/suspen...ft-blocks.html
