SUV hits tire off pickup

I love it, all the spacer haters out before they even know what happened, even though they'll never know for sure.

First, no one even knows if there's spacers on that truck. Having the wheels hanging out like that could be entirely because of the backspace on the rim, with no spacers needed at all. Plenty of guys on this very forum have the wheels sticking way out of their wheel wells without any spacers, just a negative offset rim.

Second, the rotor is definitely still attached to the wheel. So, even if there were spacers on the truck, the hub or knuckle is what failed. And of course everyone can speculate as to what it was that caused that failure. Maybe it was having oversized tires sticking way out from the body and suspension of the truck, but that's an issue with the wheel fitment. And that would be an issue whether there's a spacer in there or not. The spacer, if present at all, didn't fail. And if it was the wheel location that caused the failure, it would have been the same if a spacer used to put the wheel out there, or if the backspace of the wheel itself put it out there.

And of course, not knowing ANY of the back story on that truck, there's nothing to say the wheel location caused the failure at all. Could have been plain old lack of maintenance, or abuse, or whatever.

What I can tell You is that like almost all modern hat-rotors, there's very little offset from the hub flange to the rotor surface, & that's a ton more than stock right there.
The method of achieving that amount of offset is irrelevant, the increase in load the bearing has to survive is going to be the same.
It's hard to see what's inside the rotor, but the fail-safe that's engineered into those hubs "should" prevent total separation if the bearing completely fails. So either the whole hub left the knuckle, heat & wear caused the false-stub(2WD)/outer CV stub to fail/break off, and had to shear&clear the caliper bolts&caliper.
Either way, that was a spectacular fail & bad timing for the Kia, I'm very glad they basically walked away from that one.
