19.5 tires

So-Any problem using the 92 or later aftermarket dually alloys on a 75-88 dually?

I understand your reasoning, but a 19.5 wheel is tremendously heavier than a 16 inch wheel, and the 19.5 tires are also alot heavier than the 16 inch tires because they have such thick sidewalls, I don't care if they are lower profile.
I have all of these tires and wheels sitting next to me, I'm not guessing or using logic..... 19.5s are very heavy wheels and tires.
