Meh, I'm just saying that this wasn't an issue (at least not a well publicized one) years ago. Now the big name tire stores have charts in the showroom showing "safety" concerns starting as early as 3 years. That is way more to scare people into buying new tires than it is about safety. One guy's opinion...
I used to order vehicles for a Ford dealership in the late ‘70s and early ‘80s. That was when pickup trucks were primarily used as trucks… It was not unusual to order trucks with M&S on the rear of 4x2s and all around for 4x4s. I don’t recall “all season” tires being a thing then.
. With that I specked the first truck the dealership had with bucket seats… They used full size Bronco seats, mats, etc, in the pickups… I loaded it up with all the chrome and stainless do-dads available… 351 4-speed with Coral paint (bright orange). People went nuts when they saw it. I saw the truck at Home Depot maybe 10 years ago and waited to speak to the owner. He was the second owner … his neighbor was the first owner and aged out. It had been professionally repainted in the same color and he added a Bronco console but otherwise it was stock and it looked great. There was a yellow and white two tone that I gave a similar treatment… automatic. My mother worked with the original owner and the wife of the second owner. 
Ended up selling the owner of the laundromat a car… 
The Mrs had michelins on her Ford escape. Maybe 3 years old and low mileage. We had bought the car used from a dealer. She was going to drive to North Dakota and I had my mechanic go over the car. He called and said all the tires had dry rot cracks on the inner sidewall. Tires and tread looked great. He told me he saw it a lot with michelins. I had put Michelin XZX on my 74 pinto station wagon and put close to 80K miles on them. They stihl passed safety inspection when I sold the car to a buddy.

In general I don’t mess around with tires that are used on the road.. especially the highway. The truck I inherited hasn’t gotten much attention yet due to the elder care time demands… Back when I was putting 35,000 + miles a year on my commuter car the car had pretty much daily inspections! You could tell they were highway cars by looking at the windshield… they look sand blasted! Retirement decreased the miles a lot but the majority are still highway. My Accord turns 10 years this month but only has 60K on the clock… I used to do that in 20 months. I do NOT miss the time and expense of the commute!
Safety is my number one priority also. We wear tires out before they age out but if they're questionable I just change them. My family's(and other's) lives are more important than cheap or questionable tires.
Do you stack to the center or just throw it in the middle?
That’s a huge rim @75 inchesThinking of tires... just realized there's 2 load range c tires on the new truck.all the tires are shot anyway and bigger then I'd typically put on a truck these days. Try to find something in the 285 70/75 range for it.
