While you have towed with a Tahoe and Suburban in the past, were they equipped exactly the same?
What are your tires inflated to? If your previous Suburban had the P265/70R16 wheels/tires, they most likely had a recommended inflation of 35PSI. Your newer Suburban with the P265/70R17 probably has a recommended inflation of 30PSI (at least my Yukon XL does).
No need to go to the E rated tires, just inflate your tires to the max pressure while towing, most likely 44PSI. You can move to the E tires, but don't inflate them to the 80 PSI because your wheels are most likely not rated for that.
I would also think you are light on the tongue weight. Based on your numbers you are at less than 10% (560#). Increase that some and this should help. I myself wouldn't jump to the 15%, but start with something in the middle like 12%. If that doesn't solve it but there is improvement, then add more from there.
