How often farm truck run at 70 mph for several hours?
A lot of life was close to home but it went to a few cattle sales and it might have gone over 70 a time or two.... for an hour or two:) That truck had a hard life even before we owned it because we bought it as a totaled wreck and rebuilt it.
As a retired engineer that did some stress/environmental testing for weapon systems that went on fighter aircraft I know that a lot of "failures" were due to setup errors (I know... I made some of them) and had the system under test been properly fastened the break would not have happened. One such test cost us tax payers a lot of money as things that had been in service for decades got replaced/scrapped to "prevent failures" even though the vibration levels were bogus, the system was improperly mounted, and I had tons of data to back it up. The powers to be just wanted to be safe because a failure had occurred. That was almost 30 years ago and it still irritates me at the waste of money.
I guess I just find it hard to believe most cast rims of different sizes and designs from ford (only ones I looked at) have the exact same load rating. Like I said though.. the wheels/tires I run now are within their ratings.
