I can share from experience to remember to not go over 7 years old with tires. I had heard this many times but didn't pay attention. I blew out a 245/19.5 load range G Goodyear on the rear and the tires were 8 yrs old. Had to replace the side of my truck bed, thankfully was covered by insurance. My current Hankooks are 5 yrs old, and will be replaced in 2 yrs even though they have plenty of tread left.
When it blew it sounded like a cannon going off. Was loaded with my 9.5" Lance 921 and pulling the desert race car and equipment on the trailer. BTW, I run the Visions, 13 yrs now and no issues other than one blown tire.
