Can you show documentation to the contrary?

How Long Do Tires Last?
The average life of a tire is determined by the conditions a tire is exposed to throughout its life - not measured in calendar years. Temperature changes, sun exposure, storage conditions, usage, and maintenance schedules all contribute to the rate at which a tire ages.
It is impossible to determine a tire’s exact life expectancy, because there is no way to account for the level of influence any one of these factors may have on a tire. However, you can defer to the vehicle and tire manufacturers replacement recommendations:
Vehicle manufacturers recommend tire replacement at 6 years
Tire manufacturers' warranties expire at 6 years
Tire manufacturers recommend replacement at 10 years, regardless of tread depth

BRMA members include manufacturers of tires, tire related products, and other rubber and polymer based products in the United Kingdom. The BRMA “strongly recommends” that previously unused tires not be used if they are more than 6 years old and that all tires be replaced 10 years from the date of their manufacture.

Remember I said "10 years seems to be the LONG service recommendation for passenger and LT truck tires."
