Yes you're right, but if i build a buggy with panther Komodo tire, this tire is the same diameter than regular 1/8 scale buggy, and if i compare the weight of this tire, mount on Ofna widht offset wheel with my 2.2 badlands mount on Traxxas nitro rustler wheel, it's only 20g difference /wheel. Not too bad, so i don't think that put more stress on wheel bearing.

I think I will get a T4 and convert it to J82. Be alot cheaper, may not be as big but big enough
