to be fair , it isn't out of the question to run such a massive diameter but in the KM3.
If they're anything like the KO2 , the things are lighter than most.
yup, I checked. the 39x13.50R17/C KM3 it looks like the guy has is sitting at around 88lbs per tire. A Nitto 37 D carcass is heavier than that , I'm pretty sure.
Now, those creeper BLs weigh a lot more , heh.
my point being , if judicious with that jk skinny pedal , our friend will prolly be ok. I'd still want rcvs and suitable housings if I was gonna sling that much wheel. I'd go w a 37 and lighten my wheel choice if staying on the built 44s.
