A question for our experts:
There have been numerous failures from day one with the ground-up LT235/85R16G tires designed for trailer service. They are almost exclusively used on 7000# axles and should have the load capacity to live out their expected life expectancy but are falling short of it. The leading manufacturer has made at least one major attempt at resolving the problem with limited success.
What do you guys think about that steel cased tire? I’ve wondered about it’s regrooveability feature. Even though it has shallow threads it still has the extra tread depth to allow regrooving. Is that presenting a heat problem when the tire is near it’s operational limits? Do you think regrooving them early would help in extending their life expectancy?

FE,
I know you don't think Roger answered your question in his blog - but he did, just not directly.
No, the regrooving feature doesn't add much in the way of heat to the party. Steel casing tires are already quite thick and that additional tread thickness is small by comparison.
Like Roger, I also think that the problem for RV tires is time not wear. Regrooveable tires would be fine for a truck that would wear out a tire in 6 months, but has little value when it takes many years.
So, no, I don't think regrooving a tire would extend its useful life in trailer service.
