Why serious? Most folks have a favorite tire that has worked well for them for a lot of years. But the F450 19.5 tires are not normal tires, they are an in between tire. Not quite a truck tire, but definitely not a pickup, SUV, nor passenger car tire.

Winter tire. Believe it or not there are state laws written about tires and if they are usable in snow conditions. Most places we go require that in the winter 4x4 vehicles have "winter tires". Often time "All Season" Tires suffice. Different states, different individual requirements. I just have to be careful about this. What I don't want is the super duper mud grabber tire, I travel 96% on the highway, and only 5% on snow and ice, but I still need the correct designators.

My F450 came with Continental HD3 tires. Pretty good compromise on traction and durability. I am pleased with them. Well, once I got the chipping issue resolved, around 25,000 miles the front end was getting really "cupped". I spent some money on rotation, balancing, and alignment, and the problem has gone away. There was a lot of talk about weak shocks on the F450, but I didn't find that to be an issue.

I like the Goodyear G622 tire, but I am having trouble finding traction info on it, is it an all weather or snow tire?

Firestone makes the AT2 tire, another possibility. More research needed.

What's hilarious is that when you do tire searches none of these come up, you have to specifically go hunt them down.

I wouldn't mind replacing all 6 tires, but around 25,000 miles I got a nail in one tire in a location that the tire guys told me could not be plugged. If you don't know then you have to believe what you are told. It was near the sidewall. So I got 2 new HD3's. If I get 4 new HD3's then I have half worn tires on the inside of the dually wheels. I kind of prefer getting all new tires all at once.

While price is always a concern, it is not a limiting factor. I want to put really quality tires on my truck.
