Isn't a 22.5" rim kit going to leave you with a 35-37" tall tire? You may be able to stuff 35's in your wheel well, but I suspect even those may need a lift to not rub at full lock. Do you really want to raise the COG of your setup? Do you tow with your TC on the truck? Going to a 35" or taller tire may require gearing changes in your axles.
There are plenty of 19.5" rim choices that will give you 4500 lbs or more capacity per wheel in a 33" tall tire. This option would cost you around $3000 for a set of six rims and tires mounted and balanced with new lug nuts and center caps.
