Ask yourself , when using a chain for pulling or lifting , do you go by the working load limit or the breaking load limit ? ( One of the few items that actually gives you that information . )
Let me put a slight twist in it:
A chain has a marketing, or "recommended" load of 500 lbs. But wait, call now and we'll sell you a Super-Chain with a recommended load of 750 lbs.
You dig deeper, and find the real OEM steel supplier of the chain links specified a working load of 1000 lbs, with a breaking load of 8,000 lbs.
Which number to you follow? The "weight police" would say 500 lbs, because that's in the "owner's manual". Some of us would like to push 1000 lbs, because that's the hidden engineering spec that the re-brander does NOT want you to see. No one is pushing for 8,000 lbs, in fact, axle and tire manufactures do not even list breaking limits.
With chains it's simple, but vehicles a lot more difficult. All we have to do is look at instances where the OEMs themselves magically raise "tow rating", with ZERO mechanical changes, in the midst of a marketing war (F150 vs Titan early 2000's, Ram vs GM vs F150 early 2010's). Then there are vehicles that are magically rated lower in North America than Europe or Australia (mostly SUVs), knowing we're a sue-happy society...
