Michelin Tweel

Right now their pricing is not that far out of line for the application they are in. I just priced some Air Boss tires at our local dealer for comparison and they were $800 each. The Tweel is a couple hundred more but is retreadable, rides nicer and gets better traction.

I got some answers from Tweel on the life of the poly "casing".

They are working on their legal warranty right now, but they will essentially be covering it for the initial tread life.

They poly is rated for UV exposure to 30 years and millions of load cycles. It is rated to operate in temperatures ranging from -40*F to 266*F.

The Tweel can operate with many of the spokes damaged. There is not immediate fail if any one of them breaks. Diminishing performance will be noticed with each injury the Tweel sustains until it is decided to pull it out of service, but it will continue to operate with a lot of damage.

Making sure to get them retreaded before the tread is completely smooth is important as well to avoid hitting the steel belting.
