I thought I would share my experiences with my latest modification, the eddition of 19.5 wheels and tires. These are available for Dodge,Chevy and Ford as a DIRECT BOLT UP thru Rickson and can be seen here Rickson tires and wheels I have no affiliation with Rickson and do know that 19.5's are available thru Alcoa but are not a direct bolt up, an adapter plate is necessary for all 3 truck brands.
The reason I went with 19.5's is for the load rating, each wheel and tire is rated for about 2 x's what my oem's were good for, I ocassionally have my GVW around 32K and have been as high as 36.6K, I felt the oem wheels and tires were the weak link for this payload and am now comfortable with what I have.
I am running the Toyo TY 303- 285x6.75x19.5 they are 35.2" tall and I did have to install a 2.5 lift on the frontend to allow turning clearence for them, at the time of installation I opted to install new control arms from DT as well as a new adjustable track bar and bracket,I also had to installe a calibrator to correct my speedomotor and a set of RS 9000 Rancho shocks.
I have 3.55 gear ratio and run with a 6 speed transmission this gave me some options for my towing needs as well as cruzing speeds while empty. My rpm's run 1600 @65 mph while in 6th gear, this is great for economy while empty, in 5th@65 mph it runs at 2200 rpm, this is a great sweetspot while towing a load, havent had to downshift from 5th yet with my 5er on mountain passes on 9% grades.Although I have never dynoed I believe I am around 800 lb.ft. of torque.
My truck weighs in at 9660 lbs without me in it and I get 20-21 mpg empty and 16-18 towing my 5er pending grade %, my gvw of truck and 5er is right at 22k.
Here is a pic of the 19.5 vs the oem 16x265
