Drums such as toms, snares and bass drums are known as non fixed-pitched instruments. They aren't meant to be tuned to specific notes. Tympani and even Rototoms can be tuned to a specific pitch, but the acoustics behind the drums on the kit really aren't designed for that.
The best way to tell the resonant note for a drum is to suspend it with your finger inside the shell with the heads off and tap the shell. You'll hear one note that rings slightly longer. That would be the resonant tone. That doesn't mean you should tune it to that note, though. Two drums of the same size and wood can have different fundamental tones because of different wood and glue densities. Try to find a range of intervals you like.
There are drum 'tuners' per say, but I prefer to finger-tighten the lugs and then cross tension each lug with a key to get to the pitch I like. After I'm in the range I set the drum on the floor and put my finger on the exact center of the drumhead. Then I tap at each lug and check the harmonic of the pitch at each lug. I then go up or down until the harmonics are all the same. Once you've got both heads of a tom to the right pitch and harmonic, no overtones are present.
