Retreads except on farm equipment (don't know if any are out there) and inside tires on semi trailers, are outlawed in Indiana.
in the last couple years the federal d.o.t made it that any tire 10 years or older can not be retreaded for highway use. it can be retreaded for off highway use, yard switchers, mine trucks...etc
would say that 99% of our customers stop retreading their tires after 7 years... by that time they have been retreaded 4 times..
