There is still quite a few gmc owners running 16.5 wheels and Firestone
Transforce tires on them. Problems arise when you have tire trouble on the
road and a suitable replacement tire cannot be located in a timely manner.
Also, the 16.5 size is not a fast moving product in a Firestone store, so
their in stock inventory tends to age out on the shelves in some locations.
16" tires are much more popular, so that is not so much of a problem nor is
availability. If you shop for used alcoa's, watch out for recalled wheels.
There have been at least two recalls on them, I don't know the serial
numbers affected or dates, but someone here will know. As far as I know,
the Eagles have no recalls. Try to get HUB CENTERED wheels if you can. Much
easier to mount and they stay centered on the coach very well. Lug centered
wheels will work, but require very specific lug nuts. Just what I know.
