Is there anyway that I might be able to haul a set like this in my Prius without breaking down the rim from tires?
They will all fit in the back seat, no problem. You might want to lay down some sheets, blankets to protect the surfaces.
I talked with the owner. He said he took a hit to 41 mpg. He was not running LRR tires so I figure the hit could be mitigated somewhat by good LLR tires.
