No, not true. - BUT -

Yes, it would, but what really adds to the cost - well, you'll see it if you continue to read.
In a typical factory, (doesn't matter what they make), there are inspection points all along the way. Incoming raw materials, in process, and final inspection. Each of the inspections has to have an appropriate type of inspection. Obviously one can not do a *test to destruction* for every finished product, because there wouldn't be anything left to sell - so a sampling technique is used.
On the other hand, visually inspecting every tire is not only possible, but I don't know of anyone who isn't doing that. I've heard reports that there are tire manufacturers who don't do any final inspection, but not only don't I believe those reports, they don't make sense relative to the cost equation - that is, inspecting every outgoing tire can prevent reoccurring problems from reoccurring, thereby increasing the cost.
Where Michelin seems to be different is their willingness to discard finished product that doesn't meet their quality standards. It's not that other tire manufacturers don't have standards, but that their quality standards are different.
What is interesting - at least to someone like me who was aware of the situation - was that if the company I worked for could raise its prices 10%, and then throw away the worst 10% of its product, we would have had Michelin quality without the Michelin price. In other words, I think their price is out of proportion. (and a side note: If that is true, then Michelin doesn't have the ability to manufacture superior product. They scrap their way to high quality.)
