CapriRacer and Tireman9,
Thank you for taking the time to explain the complexity of what is thought to be a simple question about tire age. It is much appreciated.
The manufactures of ST tires sort of hint to a possible life in their warranty. I have not seen every warranty but it seems that 5 years is found often as a tire warranty. Some slightly more some less. Weather checking seems to come up as 4 years or is not mentioned but the warranty stops at 5 years.
FE found this link for me that I could not find. On page 14 it states 1/16" (2/32") is the max depth of a side wall crack and then it needs to be replaced. This is the 1st I myself have seen a rating. It did not mentioned thread cracks with is what showed up in my last 2 sets of Maxxis ST radials at year 4.5

Ex, Can you find the warranty on line? I look today and could not find it that I knew for sure it was for ST trailer tires. I wanted to see what they say about "weather checking". Some tire companies mention it and some do not.

While we do not yet have a simple answer to when a trailer tires should be replaced, we at least understand the situation better.
For me and towing mainly in Ohio, it appears the 5 year thought is about the expected life. If you get 6 or 7 years it may be luck. The damage to the camper from a blow out can be often times be worse then tire which you need to buy anyway. Since I deal with machinery for a living and believe in Preventive Maintenance programs for wear components, why shouldn't a tire be any different then a brake lining, oil change or any other consumable wear parts. Replace them before the fail.
Thanks again.
