Widest tire on an Open Pro ??
How wide a tire can I safely put on an Open Pro rim? I'm guessing 32, but hoping for 35. General purpose, utility use including commuting and general dinking around.

I've run 2.35" tires on rims narrower than an Open Pro (Matrix Mt. Titan, a rolled-down version of an Iso-C II). I'd go for the 35's without a second thought.

Open Pros are favorite cyclocross rims and are typically fitted with 35 and 37 mm CX tires.

I'm running Mich. Jet 700-30 cross tires on CXP-33s. The CXP33s have just about the same width as the Open Pros. These 700-30s are wider than most 700-35s. (So much for standards!) I would feel safe doing what as you wish.

But the main problem with going slightly over isn't any kind of catastrophic failure, it's that the edges of the tire will be "squirmy" from bulging over the rims... this is common on mountain bikes as Sheldon's page points out. If it seems to work okay, then go for it.

Now the frame, some frames, are designed for a certain tire limit, and going to a wider tire, will cause it to rub on the stays or the brakes. I would say make sure you have at least 2mm on either side preferably 4mm and the same for the brake and chain stay bridges although you want more like 8mm of room there.

I agree, check the frame clearance this is what mine looked like with the 38c's on it
