The truck deck builder I'm using to do some work on my 550 U haul build suggested going to aluminum 22.5 wheels and a low profile tire. This would be using an adapter bought online. I did some googling and there are several tires in the 255 70 22.5 with a total height of 35.5 ish inches My stock 225 70 19.5's are 31. . weight rating is 5510 as a single. I'm thinking I could use them as singles and have enough capacity. Anyone try this yet? I can get 4 used aluminum rims for about 450.00 for the 4. Java you look into this?
