Is there a name for this yet?
Does the following happen to any of you? If so, do you or your bike community have a name for it?
When heading down a rocky trail, at speed, the front tire hits a rock and instead of glancing AWAY from the rock as a non-plus tire would, the tire wraps around the rock and shoots the front wheel TOWARD the rock.
I've been calling this phenomenon "tire wrap." I am not sure exactly what causes it, but I think the tire carcass is so large and under such low pressure that the tire deforms and creates a new contact patch that has enough traction to pull the wheel to the inside. In contrast, a low volume tire with high pressure can only bounce off an object under the same circumstances; speed, obstacle shape, angle of attack, etc.
Hopefully, someone else has experienced this too and I'm not going crazy because I'm spending to much time riding my rigid single speed.
I call it steam rolling.

As little bike as possible, as silent as possible.

Monster truck effect.
Downhill lazy boy riding.
Preload the bike before that rock, then *just* as the tire hits it have your weight going up instead of forward. The result is what I call 'splatting' -- using the rock to kick the front wheel, and then the rest of the bike, into the air.
Link a bunch of these together back-to-back-to-back and you can have a damn good time motoring along a rocky trail.
More fun to go over stuff than around or through it...
it's a similar sort of thing when you're riding in deeper snow on a narrow track that's packed, but you at least occasionally brush against the unpacked snow at the edge, and pulls you even more off the packed surface. I don't have a specific word for it, but it is a thing.
Rocks in my area tend to be slippery, so I don't generally get the same effect on them. The tire tends to slide right off if I brush against it. Even if my intent is to ride over them, if they're a little bit angled compared to my approach, my tires will often slide off. Dry, wet, doesn't matter much.
