Rear tire clearance on '06 Stumpjumper?

The rear tire clearance on the SJ looks kind of tight. I do not think you could go with a much bigger than stock tire. Anyone have any problem with mud caking in there?

No clearance problems for me. I did have issues removing the rear wheel with the tire inflated. I installed a Panaracer Cinder and have no issues since.

I took off the stock Adrenaline tires (which looked huge) and put on my faves: IRC Mythos XC 2.1K. Tons of clearance to go with the grip.

You might be able to get away with a Weirwolf 2.3 in the back, I'm running a 2.1 right now and there is room to spare. It might rub the neoprene chainstay protector, but it should be okay otherwise. I've seen 2.4 Timberwolves on another S-works similar to mine, but he couldn't use the granny gear because it rubbed the derailuer.

punga!

How big of a tire are looking at running....

it depends allot on brand and size, as sizes vary so much between manufacturers. I've run up to a 2.3 Continental Vertical Pro on my 05 Stumpy with no problems. I'm sure there are larger tires out there that will work. If you are worried about it I would highly recommend Shiggy's site. He has allot of tires listed there by brand and gives claimed and actual widths. The link to his site is below. With that reference as a guide you can measure between the stays and then check a specific tire and determine whether or not your should have any problems before you buy. If you ride in really muddy conditions I would recommend going with a tire that will give you a little extra clearance between the stays. Anyway, Shiggy's info is quite accurate and should give you a pretty good indication of what will work.
