Just checked. My T-Serv 28's measure a full 28mm on Velocity A23 rims. Also have a set of Pasela TG 32's, mounted on 25mm (O.D.) rims, they measure 33.5mm wide so a little fat. Both tire sets are 1-2 years old. The T-Serv used to be sold as a lighter weight but slightly tougher urban tire - the difference was in the belt, sidewalls and the rubber. I think they changed Pasela TG's suffix to PT a year or so ago. Both tires belts are now listed as the same but still different rubber between them. They're both fine tires and I doubt I could tell the difference in ride.
