I should only gain another 2" with this lift, maybe 3" at the most with the new springs. I'm on 255/75-17 (32.5") so I'm in no rush for anything bigger. Looking to eventually go to a 33x12.5x17 but only after my tires are worn and I have my finders trimmed.Nice, can't wait to see that lift installed! Your current tires look really new. Will you get new ones when you install the lift?
