This was long before tubeless and 23mm internal rims. We ran these tires at 25-30 psi and never rolled a tire off the rim in several single track turns. My only thought for the OP is will a 28mm fit ?. Lots of places tfor it to hit the chainstays, rear brake, bottom of the fork, not to mention issues getting past a set of dual pivot brakes while inflated. Rim size would be the least of my concerns.
