No i use dugast with vredestein treads with a special wall coating,tufo xc3,dugast rhino 47mm with aqua seal and some prototypes from challenge.
The rims i use weight 300gms dead and i run them on tune hubs and xtr hubs and a2z hubs.for the 1275g is the tune…
they're better because they dont slipp on the rim,they deform better and weight is comparable once tyres are stanned up.
