My luck ran out.

Ricky,

Must say , I'm a little bit surprised at the "piling on"
that took place on the first page of the responses. One of the
strengths of this forum seems to be... admissions of guilt
warts and all, and then hear tales of similar woes...

Before the era of forum Solomons, I use to gauge my TT tire life
based on remaining tread... kind of grew up that way... I had
no idea that the sidewall life expectancy was the limiting factor...
just didn't. I ran my oem issue tires about 9 years before I changed
them out...still had good tread left.

Here's a blast from the past... growing up, my Dad would change out
re-treads as he saw fit, one at a time, towed a 22 foot inboard wood
boat and a load of kids in the bed of a plywood covered Ford Ranger.
He replaced the tires with re-treads... based on the responses to this
thread he should have been imprisoned for child endangerment.

you are forgiven... drive on.
