Should not not have a problem tucking them on the square body.
The wheels measure 21" total width without tires on them and 11.25" from inside of inner wheel mounting surface to the outside of outer wheel lip.
Price is for all 6 and we cannot sell them any other way.
The styles are just the classic (058) and the spoke (056) right now. They say more are coming but may take a while.
I wish they could be cheaper Kyle but they changed some things like center caps and some other safety features that made the price rise over the years of development.
