I'd prefer to tow with 20's over 22's myself but you could do a 305/45r22 Nitto Terra Grappler G2 and not lose any load rating. We put simple leveling kits (2" Ready lift) which enables you to do a 20x9, offset around a +18 with a 33x12.50/20 ( Nitto, Toyo, Mickey Thonpson....). In 22's the same but most 22's will be 22x9.5, look at Fuel wheels, XD, Moto Metal....in these sizes the 22's will ride just as good as the 20's and the wheel and tire selection very similar. With the mild 2" leveling kit you can run a 285/50r22E Terra G2. Your good either way, good luck!
