Tire longevity

So the way I read it is he had 2008 tires, and thought they were a good brand and manufacturer, so he bought 5 new ones of the same hoping they would be his last.
Always someone smarter than everyone else, in their own mind.

You talk as ignorant as you read--I don't think he said he USED them for 14 years anyway, only that they were that old. I guess you are just "Mr Perfect"

I am sure the OP was not looking for any criticism, but writing that tires are ok for 14 years misleads others who don't know any better. Poor tires are a major cause of accidents for RVs. Heavy loads and old tires are inviting disaster.

"I don't think he was looking for a smart a-s lecture but just making a statement. "

Exactly.

Pretty good service we thought so we bought five Rib replacements which should last a lifetime since we are both in our middle 80's.

Someone in their 80's should know better. There are a lot of factors that can lead to premature wear or failure:

Road hazards - A pothole or other hazard can result in immediate failure. Even something such as driving on gravel roads can take a toll.

Punctures - Anything that punctures the sidewall will result in instant failure and cannot be safely repaired. I even had a major slice in the center of the tread due to a piece of sharp volcanic rock.

Heavy loads and underinflation, especially at high operating temps can greatly reduce life or even result in immediate failure.

Tire age - tires dry rot due to UV light but mainly just oxygen. Most tire manufacturers recommend replacement at 7 years or less. That is especially true for tires operating at high loads, but dry rot can kill a tire regardless of load. For reasons I will not try to explain, RV tires are often at much higher risk for dry rot because they are not used frequently and will dry rot faster than tires that are used frequently.

Maybe at 80 years you just don't care anymore. I am in my 70s and would like to live considerably longer.

I wouldn’t trust trailer tires manufactured in 2008 after 2012 or 2013. You were lucky IMO.

Good service, yes.
I used to run XPS rib on my work truck and got great service out of them.
I just replaced the Michelin Defenders on my dually after 80,500 miles. Best tires I ever had.
