We investigate coherent electron transport through single-and double-barrier structures in tilted Dirac surface states, where the tilt is induced by an in-plane magnetic field. In conventional Dirac systems, Fabry-Pérot resonances are strongly mode selective due to their dependence on transverse momentum. We show that the tilt suppresses this dependence and enables a simultaneous alignment of resonance conditions over a broad range of transverse modes, giving rise to a super-resonant transport regime with enhanced transmission and pronounced conductance oscillations. We demonstrate that this effect originates from two distinct mechanisms: in the single-barrier case, it is driven by an enhancement of the available propagating mode density, while in double-barrier structures it arises from phase-coherent selection of modes satisfying a Fabry-Pérot resonance condition.
