E70 X5 is rated to tow 6k pounds in the U.S.. 10% advisable tongue weight would add 600 pounds in theory to the rear axles, assuming weight bias/distribution remained equal front-to-rear when towing (probably not realistic, but with auto-leveling I don't think it changes much based on my towing experiences with this chassis.)
What is the average weight these wheels are rated to, then, I guess is the next question?
Thanks for the help!
