i might have found a solution to this: renegade rc do a 14mm hex to suit the cen and some imex wheels for the tmaxx have a 14-17mm adapter included with the set of wheels. these adapters renegade tell me, will work with any 17mm wheel.

as i wanted tmaxx wheels anyway, for an mt setup as well as buggy wheels for a sort of 1/8 setup and therefore the 14mm hexes, im laffin!

just thought i would post so people know in the future. (if anyone cares - lol)
