I am looking at changing to a 19.5 tire, I have a 2013 with stock ride height. I have searched for two days and can't find out if a 245/70R19.5 tire will fit without any mods, I could go with a 225/70...
You would likely be fine with those. Worst-case you'd have to crank the torsion bars a little. They're only a 33" tire and they're almost an inch narrower than stock.
