Any 1.9 inch Voodoo/bully alternatives? (pin treads)

[punktaconyc]

I have been looking both online and in stores for a while now for an unmounted 1.9" ID, ~4.2" OD pin-style crawler tire that looks and performs like a smaller version of the Team Ottsix Voodoo or the RC4WD Bully. The inner diameter of the tire, 1.9" vs 2.2", actually does not matter as much as the outer diameter. The outer diameter can be NO GREATER than ~4.3", whereas I can get both 2.2" and 1.9" rims for the inner. Do you have any suggestions? If there aren't any tires of this type, do you have any suggestions for possibly modifying and shinking either a set of Voodoos or bullys? I am a beginner with any sort of tire modification. Lastly, if you have no suggestions for my previous questions, could you point me in the direction of the best 1.9" ID ~4.3" OD crawler tires that have a super soft compound (unusually soft as this is for an unusually light crawler). Thank you very much and feel free to politely critique this post as it is my first on this forum.
