BF Goodrich all terrain tires for towing

[madeforeachother]

I have a 2003 Dodge Ram 2500HD and have been running 285/70r 17 inch load e all terrain tires for 25 years on past and present tow vehicles with no issues. The last time I replaced the tires was 2013 and needed a new set in 2018. The problem is BF Goodrich changed the style of the tire in 2014/2015 to KO2 and when I had them installed I witnessed a big change in the truck handling with swaying being the problem and I feel like I have no control driving. I have lowered the tire pressure and that helped a little but still am not comfortable towing like I was before the new tires were installed. Has anyone experienced this problem with any tire design change and what was your solution other than getting different tires? Thanks for any input.
