with rim brakes that wide, you may run into clearance issues. the brake arms will be spaced so wide the cable across the top of the tire may not clear the top of the tire. the farther out you push the arms, that triangle becomes very short...
i once was running rim brakes on 32mm wide rims and would hit my heels on the brake arms all the time with them so far out.
