All psychedelics have cross-tolerance. Tryptamines will generally have most cross-tolerance with tryptamines, and phenethylamines with phenethylamines. The closer the effects the more tolerance is usually noted.
The NBOMe series psychedelics are all phenethylamines so they share a strong cross-tolerance with other phenethylamines. Also, due to the fact that NBOMe series chemicals tend to produce longer and stronger tolerance, I'd really make sure that you do take a 2+ week break after your NBOMe series trip if you want to experience the fully fledged effects of the next psychedelic you plan to take.
