Firstly, there are no 100% flawless products to be found on this or any other planet and 1% is phenomal given the inherent falablity of man made products.
Additionally, it would be a 1% failure rate if the tire company only makes 100 tires a year....I'm guessing the likelihood of that frequent an occurance of failure is somewaht exaggerated. A "1 out of 100 tires" would be more like 20-30% failure rate for an average tire company. Not the same.
Secondly, a tire is not a consumable item, it is a car part....we don't eat them
Besides, something as serious as bodily injury or death has not, at least to my knowledge, ever occured with TCA, but I get your point: It would not be a good thing.
Again, there are no 100% guarantees on anything we buy.
Most volume manufacturing industries speak of achieving "six-sigma" defect rates these days. That means fewer than one defective part in one million. Three-sigma, routinely achieved level of quality in manufacturing, is a 0.3% defect rate.
I don't understand your comment concerning the failure rate for a tire company. One out of every 100 made works out to a 1% failure rate, no matter how many tires are made. A 1% defect rate means one could expect 10 defective tires out of each lot of 1000 made, or 100 defective tires out of each 10,000 made, etc.
And tires
are consumable items. They wear out and have to be replaced.
I dont' recall what the failure rate was on the Firestone SUV tires involved in that big recall some years back, but I think it was several orders of magnitude better than 1%.
Yes, TCA never killed anyone, but fine wine is one of the few consumer products I can think of where defect rates this high are tolerated. My own profession, software, has an even worse track record, of course. Not only do we have a worse defect rate than even wine closures, but we have the gall to make the consumer pay for fixing the defects. What a racket.
