My 2015 F350 SRW 4x4 came with LT275/70R18 tires rated at 3640-lbs, and the wheels (rims) are rated for 3590-lbs. Ford publishes a spec book, and if you can find it via Googling, it has all the specs you could ever want (e.g. tail gate weight).
I pondered going to 19.5", but the jump in total tire/wheel weight can be substantial and complicate DIY roadside repairs, and my friend at a Ford dealership warned the additional weight can cause problems with the spare tire cable hoist. 19.5" tires are also narrower, which I don't find favorable for my light off-road driving on soft/wet roads. 19.5" tires also have harder rubber, and while some are marketed as "mud and snow", I haven't found one yet that is formally rated M+S, which in some states is the minimum standard for avoiding chain-up on snowy passes/roads.
