I agee with 3B, your front tires are 8.25x20 which means they are tube type and are mounted on some sort of a split/multi piece rim. The 22.5 are all tubeless one piece rims and are the direct replacement for the 20" rims.
You want to replace your front wheels and tires asap with 9.00x22.5 tires which is the same size as your 8.25x20.
