First thing I would check is date of manufacture. I nearly had a front tire blow out on me when a belt broke. The front of the truck developed a nasty shake over the course of a 200 mile round trip on the freeway. Tires age whether you use them or not. Mine was an unused spare that still had the nubs on it. Since then, I've avoided buying used tires. Although, where I live, a 50% tread set typically lists for only slightly less than 50% price of a brand new tire, so it was never much of a bargain to begin with.
The factory steel wheels are the strongest.
I have had many tire issues.
One trip to see Calvin we had one seperate, he ordered me some 235-85 16 bridgestones , commercial casing, very good tires,
Dont go with house brands for hauling a camper, my single wheel with the camper on was 7600 rear gvw. Right at the axle limit and tire limit. I like a bargain but bridgestone, continental, michelin are the way to go on hauling weight.
Basically you need a truck tire not an LT.
That would have been good enough for me. I'm sure that he knew tires better than most of us do.These tires, all six of them, received Calvin's seal of approval.
Those are some pretty good looking tires.
