Tire Size Upgrade and towing advice

Just got a 6.7 f250 with the stock 275/70R18 tire size. I tow often(landscape company) and often times it's 10k+ weight. I want to upgrade tire size to maybe a 295/70R18 or 33's. Really just need something a bit wider for my taste. In my past experience with Chevy trucks I went from stock 245/75/r16 to 285/75r16, and the tires sway very much when towing or just driving.

Would going up to a 295 or 33 make much difference in regards to handling? I know I'm going to have a little less mpg and all that, i'm just concerned with the driving factor. Didn't buy a truck for mpg, haha. Obviously would get a 10ply tire, something more aggressive but just an A/T tread. The wheel widths seem to be be in line with what the tires are rated for, just need some real world experience.

OEM are 33 if you measure them. Lots of folks running either 295/70-18 12" and 285/75-18 11.5" (closer to 35") without issues. Both sizes are 4080# load rating if you check cooper.com or tire rack, etc.

I tow weights similar to that on occasion including a 37 foot bumper pull travel trailer with 37x12.50r18E Nitto ridge grappler tires. Never experienced any type of sway or stability issues. Always feels planted and secure.

I run 35X12.50X20's on my 2006 F350 and pull a 13,000 pound 5th wheel toy hauler with no problems at all.
