I've read here that though the Surly Steamroller is rated for max 38 mm wide tires, people have got wider tires on.
I'm looking to buy a pair of Schwalbe Marathon Winter tires which come in 35 or 42 mm versions. Anybody know if the 42's will fit? Will I need super wide calipers?

I'd just go with the 35s, it will be a lot less hassle for a few mms less of tire. I've got a pair of 35s(they are great tires), and I don't think I could fit much more tire into my hybrid.

Is that 42 w/ or w/o the studs? I have 1.9 snow studs from Schwalbe and they are 2.0 all-in.
Anyway, there is a thread at mtbr.com showing a steamroller w/ 42 cx tires, obviously no fender clearance at that point but it has been done.
Remember that the actual width of the tire also is greatly affected by how wide the rim they sit on is.
probably would have to use some tektro calipers with lots of clearance.
also consider your rim width, putting a tyre that's too fat and at too low a pressure could cause the tyre to fall off the rim under load.

I found instructions on fitting studded tires at Peter White Cycles (under How to Fit the Fat Ones):
He suggests 10mm clearance between the tire and the underside of the fork crown and same in the back. I have about 1cm so no problem there. On the sides I have about 5 mm on each side of my existing 35's so that's dicey - Peter. White recommends 10mm on each side.
I'll go for it and report back.
