I hate to say it but Id reconsider those toyo's. I have a set of 33x12.5' on my DD and they weigh as much as most 35's. I can only imagine what a 37 14.5 weighs. They are also pretty terrible on the muddy trails hear in wa. they dont clean out for sh#t. I hate to be a downer so I'll say they do seem pretty tuff and last forever.
Thanks buddy you are just re-affirming what my research has told me tonight. It would be stupid anyways for me right now. I'm no where near ready to run 37s yet and should be putting money towards getting there.
