Late to the reply here but I happen to have this setup. I put on Bontrager 2.4 tires on my Marlin a couple years ago. The problem that you run into is clearance of the front derailleur or shift cable hitting the tire. I slid the derailleur down as low as it could go in order to create as much room as possible. It wasn’t until I started to wear down the rear tread a bit that it would stop rubbing, and the tire pressure had to be down a bit as well. It wasn’t too annoying, and ultimately it was worth it for such a fat knobby tire compared to the skinny speed tire that came on the bike.
