First off back then vehicles were almost all rear wheel drive with open differentials. No ABS. No all wheel drive. Heck not even four wheel drive unless you owned a ranch or were a forest ranger.
Of course having different size/type tires front and back is not a concern on a basic RWD vehicle.
I think I said 4X4 could be a issue, unless you stay on slick surfaces. A 2 wheel drive pickup is real close to a basic RWD vehicle. If the tires on the back match each other your differential will be quite content, no matter the size of tires on the front.
Beyond that it depends on how your ABS system works. If it compares front and rear rotation rates you might have trouble with the ABS activating, having different size tires front and rear.
Yes, I understand that the P and LT tires may have the same NOMINAL size, but they can be different diameters.
Yes, there is a good chance P and LT tires will be different circumference. But 2 LT tires with different load range will be different height under same load. Bell, back in the '70s a stack of brand new, same brand truck tires same size 11:00 22.5s good vary over a inch in circumference.
The implication is because we did it "all the time" in the 60's and 70's, that it's not a problem on any modern vehicle, and that is incorrect.
