Really just a clearance thing. If you can get away with no boost that is fine and possibly better if the the rear is spaced 135.
Even a 2.4 should be fine. I like the fatter almost 3" tires for fast rides, they are a ton of fun and the traction is amazing, but I just got back from Annadel where I was the only ridid single speed with 42mm tires today and all was good fun. Carried the bike across a few rock gardens to preserve the rims but all in all it is amazing what you can get away it. Not faster, but certainly more interesting again on the beaten paths. Not knowing the geo on the Susie it is hard to make any solid recommendations. I'd give RBW a call to sure.
