The article says the tires last 2-3 times as long as normal. So I'm guessing about 100,000 miles? as far for the metal portions, I have no idea. I'd imagine the intervals would be similar to suspension intervals which are very long.
It sounds like ERW beat Michelin to that patents and that is the only thing keeping this things from going into production. I'm sure there are other issues, but I really wish I could try a pair.
