man is warning his fellow east end residents to take extra
care when filling their wagon wheels up with air.
resident Mike Potvin was filling up the tires on his utility
wagon on June 30 when the split rim on one of the tires
blew apart causing severe lacerations to his face requiring
more than 150 stitches, a broken orbital bone, a broken
nose, a hole in his upper palate and the loss of more than
a dozen dental implants.

tire rim broke away a portion of the bone in his upper and
lower jaw where the implants were drilled in. He may end
up having to use a prosthetic denture.

by a series of five bolts.
rim corrodes over time, the metal around the bolts weakens.
The older the rim gets and the longer it's exposed to
the elements the weaker it gets. Ultimately, it is prone
to a critical failure. If enough pressure builds up in the
tire, the force applied against the rim becomes too much
with potentially dangerous consequences.
search of split rim explosions or split rim injuries turns
up dozens of posts on the Internet. The best way to avoid
potential injury is to use a cage around the wheel when
inflating it, or replace the tires altogether before a catastrophe

wagon for crying out loud,� says Potvin.
