4x4?
I have a 2000 f-250 and in the snow when I put it into 4high the front and rear passenger side wheels spin in the snow but the driverside dont and I have a hard time getting out of heavy snow,I have manually locked the front hubs in and it doesnt seem to make any difference I dont now if I have a problem or just junk tires they are some brand from Sweden I never heard of them but they came with the truck?

unless you have a limited slip differential the wheel with the least traction spins, and that happens on both front and rear. Typically the front diff is open(no limited slip /lockers) and the rear may have a limited slip so the best you could hope for is 3 wheels driving and when both diffs are open then depending on conditions only a front and rear wheel may be spinning (least traction), it shouldn't always be the same wheels.

Real snow tires make a big difference in deep snow. There are ways to improve your off-road traction by brake modulation. It is sort of hard to describe, but, basically you lightly press the brake pedal while giving it the gas until the driver's side tire starts to spin. I have used this to get really big trucks, like empty tractor (trailers), off sheet ice. One thing to remember is your axles are kinda of biased to the right side for torque, so that is usually the side to lose traction first.
When driving in snow/icy conditions you really should deflate your tires to about 20 psi, especially with a radial, is possible. It will spread the tire over the icy surface with a much greater footprint and make it conform to the surface instead of making it a big hard wet rubber donut.
Try running both right side tires 5 psi lower then then left side. I would not recommend it for the street, but, you might solve some off-raod traction problems by running the LF and RR 5-10 psi lower then the other two tires if you have open diffs.
What I do off-road in snow is run my tires very low and if I get high centered and totally stuck on snow/ice I then inflate my tires to the max and this helps lift the frame off enough to back out over my old tracks. Especially if your front axle turned into a snow plow.
