I am building up an old specialized crossroad as a commuter/tourer and the doner bike has a great pair of 700c X 38 tires. Will they fit on a standard road rim? I have as set of open pro's and a set of MA3's and was wondering how wide of a tire can I fit on those rims. Would a set of 700c x 38 be too wide or is something like a 700c x 32 about the max before you have to get a slightly wider rim? Thanks for the help?
