It may not mean much to some, but in my toy hauler I needed 3500lbs per wheel (7000lbs axles) and only caught this detail at the last minute. I mean, shopping for Load range E, you'd think they'd all be the same.
Even my tire shop was surprised at this change.

What is the official GAWR values on your trailer's certification label.
There are three official load capacities for LRE ST235/80R16 tires. 3420#, 3500# & 3520#, all at 80 PSI. There is a FMVSS standard that covers that situation and reads sort of like this; Without documentation, they all default to the lowest value, 3420#. When the trailer's axles are certified at 7000# the vehicle manufacturer must show NHTSA documentation that OEM tires sized ST235/80R16E having at least 3500# of load capacity were installed as OEM. The 3420# tire does not qualify. When Keystone - or any other trailer manufacturer - uses the ST235/80R16E tires as OEM on 7000# axles without documentation, they MUST officially derate the 7000#axles to 6840# or less and certify the value used on the vehicle certification label.
