Jack's right-- You don't machine rubber, you grind it. Test a thick chunk on
a coarse sanding disk and go from there. A guy could easily develop his own
rig. Has to be a rigid setup with the tire running true and no deflection in
the grinder mount. Might work spinning the tire on the car; but I'd try to
gimmick some way of clamping the grinder to the axle housing and sweeping it
parallel to the rotating centerline or on a template. Or possibly mount a
front hub off a thick reinforced concrete floor (now's the time to build that
concrete walkway your wife has always wanted) and build a drive pulley mount
that attaches to the lug bolt circle. Drill some anchor bolt holes for the
grinder mounted so it can be moved across the tire profile and be reset for
deeper cuts. (Howcom Jack's ideas come out in so few words while mine take
hundreds?)
