I’m running 32s with a 2 inch lift and apparently you can fit 33s with some trimming, but otherwise your advice is sound. If it’s just barely rubbing, get out the Sawzall and/or the sledgehammer and go to town. Not sure if you want to start doing that to what looks to be a super minty Disco though - I would personally switch back to the 19s (I think they look awesome - far better than the 24s IMO), but that’s just personal preference. Those 24s must make it ride like hell too. Take a look at it at the places where it rubs (such as full lock) and see what it’s hitting and whether or not you can/want to trim that piece. If it’s just barely clipping the bumper, then maybe consider trimming it. If it’s hitting suspension components, maybe a set of wheel spacers will fix your rubbing.
