I can't remember where I saw it now, but there are a couple local places that'll do this. Interestingly, it's very similar to putting it on your rear wheel and spinning it up.
The race tire shaving places all use blade machines because it's cheap and easy, but they won't touch used tires for obvious reasons (grit embedded in there kills blades). But big truck places do shave used tires with a machine that's more of a grinder and doesn't care about the grit in there. Those tires are molded with so dang much rubber on them for life that when they have an alignment issue and screw one up, it's often still cost effective to shave it back right and keep using it.
But finding a place friendly to small tires can be the tricky part, but I know there are folks in this club who have found places. I'm curious, too, because I have some BMTs (Big Mud Tires) I'd like to have shaved back round.
