The age is also a concern, but in 6~8 years there is little you can do to avoid that heat.
There is another issue that I have very first hand experience getting pummeled by. The life of most elastomerics (rubber like stuff) is not unlimited. I have had laminated pieces go bad after 8 years in the box.
Tire companies are now saying that the best you should hope for is 8 years. Michelin says that if you want to run RV tires more than 6, you should have them inspected every year after that.

Self-serving planned obsolescence is more like it.
I have some very large, very expensive tires on some of my farm and construction equipment that are 20 and 30+ years old that have lived and worked outside that whole time, year-round.
None of them have any weather checking or other 'age' issues.
The fact is the tire companies figure the 'average' vehicle goes 25k minimum per year, at 75k or 100k they're worn out, so why spend the money to make them last anything more than 'X' miles of average driving plus a little buffer space.
