I have a set of mud tires that are clincher that I run on A23's with 105 hubs and I run Velocity Major Tom rims with tubular dry weather tires for normal racing. This way, I don't have to adjust the brakes when swapping wheels since they're both 23mm wide. Besides, my mud tires are also my spare set in the wheel pit so I want them to be swappable on the fly.

They're both on identical 32h builds and cassettes.
