Yes 22.5s are not only far superior to the old 20"tube type they are much cheaper too. That has to do with that supply and demand thing again nobody is buying then so there are no big stocks being kept anymore.
I changed mostly because my trucks are working trucks and the cost of flat repairs is much more on tube type not to mention you will have twice as many flats with the tube type.
Although expensive the change was very cost effective for me.
