Most folks will not see a reason to go to this swap. As budd wheels are common in circulation. however on some super single civilian tires such as 445 65 22.5s. They require a 22.5 X 13" or 14" wide wheel. Drive wheels are rare but available in budd in aluminum in that width. Steer wheels like found on @M920 truck aren't common and expensive to get. 445s are equal to 45.5 inches tall so it increases road speed of the stock tires. Generally the same swap you would for 395s but the 445s have much greater mileage rating than the 395s. 395s last around 40k on drive axles vs nearly 200k of the 445s. Weight capacity increase from 9300# to 12,300#

Aluminum super single hub pilot in that width are fairly common

Budd wheel for 22.5x13 is accuride # 28684

385/65/22.5 and 425/65/22.5 tires can run a standard 22.5 x 12,25 wheel which is common in budd pattern just some do not come with the 1-1/8" stud hole always on the wheel. Most wheels will have a 3/4" stud hole so be sure to watch for that.
