Roo, Yes it is. According to mud throwers website, my 28x12x12 zillas weight 27.5 pounds, which isnt that too bad compared to a standard maxxis bighorn radial 26x12x12 weights 30 pounds lol. I know between the larger rotational mass and traction difference it is alot but just comparing tire weights. I blame my higher combo weight on my steel deltas. If I went with a itp ss wheel they are lighter and would help with the rotational mass problem. Anyway So far I have have 18 gram Greaseless OD weights and sliders modded by hunterworks to keep most of my bottom end, a gold spring and as of last week a wv hotrod sheave. Even before the sheave I could turn them in all the mud around here. Now with the sheave it handles them even better. Throttle control is key with bigger tires, or you begin to brake parts lol.
If you know your tire and wheel combo post it up, i would like to see some other set ups on here. Just hop on that home bathroom scale with your setup in your hand and post it up.
