Does nobody remember "snow tires"? Back in the day most people, on most vehicles, ran rear tires that did not match the front for about half the year.
(On my pickups, snow tires in winter, then spring I would name them "Mud Grips")
As for different size F/R. 2 wheel drive, this is not a issue. 4 Wheel drive, can be a problem unless on surfaces you need 4 WD, and tires can slip
LOL...back then most pickup trucks on the road around here anywayz had OEM tires on the front and huge tires on the rear. I had no problems with the different F/R sizes with all bias ply.... or all radials.
I found out from actual experience not to mix radials with bias ply. One doesn't track the other very well. Like driving with 10 psi in the rear and carrying a load.
Fed regs require a P tire load capacity to be derated by dividing its capacity by 1.1 when mounted on a truck or trailer. A 2600 lb rated P tire capacity now = 2360 lbs so make sure that number fits the vehicle mfg GAWR requirements for that axle.
