What I posted recently on another forum regarding TW retreads after being accused of propagating "Myths and hearsay".
From the Tire Industry Association:
There has been a continual downward trend in the use, both domestically and internationally, of passenger automobile retread tires. This is due to the confluence of several factors; first, the capital expense and technical challenges of passenger vehicle radial tire retreading for a retreading facility has not been viewed as providing a strong enough return-on-investment, second, the fact that tire manufacturers do not put an effort into designing passenger tires to be retreaded
See that last part? That's the clincher right there.
Tire manufacturers DO NOT put an effort into designing passenger tires to be retreaded.
All the other tires you listed above, OTR, aircraft tires, some Ag tires, guess what? They are DESIGNED, as in ENGINEERED with tolerances, composition of materials, etc. to be retreaded. Those tires you mention, they are built with steel casings and made to be regrooved and retreaded. Huge, huge difference. Also, those tires have many thousands of miles put on them more quickly than any passenger car or truck tire, allowing for the rebonding process to adhere better.
So again, feel free to run a tire that has been retreaded though it hasn't been engineered to be. Really you are comparing apples to oranges here. I'm not trying to be a jerk, but you really don't know what you're talking about, nor do the guys up at TW who are pushing those tires.
