I think around 520 was the record going 100% to zero but with a lot of 70 mph. I actually think getting - who knows - 530+ should be possible with under 60 and a bit of hypermiling. I don't know why the YouTubers aren't trying this, seeing how high they can get, it would make a great video. They just run and gun. The first one to get 550 miles would be a big splash.
Not a youtuber but have 35" and willing to go for that drive!

 
Btw, any major impact on efficiency? Found a nearby shop with Hummer EV 18" Takeoff's that have tires sized 305/70/18. In my case I'm assuming maybe a possible gain in efficiency vs 24's, but just curious as to your experience.
Just drove today about 150 miles at 80mph, very hilly, and scored 1.7 mpkh. In town, usually 2.2. May try 70 mph on the way home. No meaningful loss for me if there is any. The truck is just better with them. Have hard tonneau as well.
 
My experience with the 305/70-18 is about .1-.2 mpKWh loss compared to the factory 24" wheels and tires. The 285/75-18 Nokian severe snow rated tires I replaced the Hummer Goodyears with didn’t change it.
I think these may be the same Nokians if your's are Outpost nAT? I originally put the stock size Nokians on but traded those right back in for 285's and happy I did. There are 295/65's that are very close to stock as far as height.

Coming home tonight was 1.81 over same road, 80 mph. My wife drove, so...maybe the problem is me :)
