For those of you not in the know:
I'm that poor basturd that has to go out and replace blown truck tires on the side of the interstate. Retreads get a bad rap. Let me give some things to think about.
A retreaded tire means just that: the tire's carcass has had new tread adhered to it. In the above horror story of tire debris, it is assumed that the tire was a retread. Not necessarily so. If you're just convinced that the tire was in fact a retread, how can you verify? Read on...
From the original poster's comments, the tire "blew" apart, leaving tire debris in his(op.tic's) driving path. This can happen with any tire!! Contrary to what you may have heard, a regular tire's tread is adhered to the carcass in a similar fashion to a retread's. This means (and I've seen this MANY times) that a regular truck tire can lose it's tread just as easily as a retread. The factors for destruction are load, heat, tire pressure, belt or cord damage, or puncture/other injury. All of these factors can affect either a retread OR a "regular" tire. Tires aren't just a mold you shoot black goo into. There are several steps involved with building tires. Carcass, or, casing construction is a wholly separate operation from tread design/adhesion to casing.
People say "retreads are bad because the tread comes off"
Consider this: the majority(around 75% from a study I read a while back) of truck tire debris you see on the side of the road will have metal cords in it. Know what this means? It wasn't a retread failure, but rather a casing failure. The metal you see are the steel belts that make up the casing of the tire. NOT THE TREAD. Tires do not have metal cords in the tread. Casings fail more often than tread(puncture, overloading). Op.tic's comments(if he accurately reported) clearly show a casing failure, resulting in tire explosion, and flying debris.
Don't blame the retread. Casing failure is more common than tread failure. This depends heavily on retreading process...only a select elete of big companies still retread tires...for a reason. Retreading process has come under heavy scrutiny. Process of retreading must be on par with new tire manufacturing. All because of more and more people with half the facts focusing on what seems like a "smoking gun" culprit.
Retreading maximizes miles per tire life, and keeps truck operating costs in check....where it matters most...long haul trucking.
The real problem with ALL tires is maintenance. If we all pay closer attention to tire condition, air pressure, and don't try and squeeze another week by filling that low tire again, the roads will be safer.

It is important to note that most of the rubber on the road comes from truck tires and is caused mainly by underinflation, overloading, and tire abuse

If you don't believe anything I've said, please take the time to read this next link:
http://www.retread.org/PDF/RonR_Wagner.pdfThe department issued a report inNovember 1999 that concluded “theproblem of tire debris along the highwaysis not due solely to retreadedtires.” In fact, the study revealed that asmall percentage of rubber on the roadactually comes from retreads thatfailed due to manufacturing defects.“Examination of the debris revealsmany of the tires (that fail) are newand have never been recapped. Expertsbelieve failure to maintain sufficientair pressure causes the tire casingsto become extremely hot andeventually come apart and spread debrisbeside the highways.”
http://www.twna.org/retreads.htm"Retreaded tires have a safety record the same as new tires and in most cases they offer a substantial cost savings over higher priced new tires. Retreaded tires are also very environmentally friendly, which is a fact not well known by most of the public."
"Since it is probably impossible to ever totally educate truckers and other motorists about the importance of proper tire maintenance, along with the importance of stopping immediately upon detecting a tire problem, the best our industry can hope for is that our members continue to educate the public about the real causes of rubber on the road."

From the EPA:
http://www.epa.gov/ne/assistan...d.pdf“ ...we do more than25,000 tire changes ayear-or about 70 tireseach day. ...Since thetreads on airplane tireswear much faster thansidewalls, retreading isa common practice.Our tires thus spendmost of their productivelife as retreads, andsince recapping producesa lot less wastethan discarding andreplacing perfectlysound tire casings,using bias-ply tiresmakes environmental aswell as economic sense.”--Robert CrandallChairmanAmerican Airlines
The debris you see on the highways is as much from failure and abuse of new tires as it is of retreaded tires. Retreaded tires have been safely used on school buses, trucks, cars, airplanes, fire engines and other emergency vehicles for years.
