Copper Cobras Tires life expectancy

[767Jockey]

I have a Class A diesel motorhome. In the motorhome community this is a very common topic, as tires on motorhomes almost never wear out, they age out. Tires are a huge concern because they're so darned expensive. A replacement set on my motorhome is north of $5000. The commonly used age to replace motorhome tires is 7 years. That's a figure that is pretty much universally accepted in that world. I imagine the same would carry through to our Cobra's as well. Sidewall degredation is easy to see, it's delamination in the tread area that can't be seen that would worry me about using old tires. I wouldn't run any tires on any vehicle I own that are over 7 years old.
