    we run a 2wd 98' c3500 dump with an L pack and 8' drop side dump with a blizzard 810pp.

    what we did was create a bulkhead in the back to keep about 3k worth of #57 river rock up against the back tailgate as ballast/traction aid. the back end has 4 235/85/R16 E Range BFG All Terrain KO's.

    the truck does about 50 of our 150 resi driveways and a few commercial lots and does pretty well overall, it just depends on the conditions, heavy wet snow will stop the truck occassionally or if you get the real cold powder that glasses over after a scrape youll be spinning but can usually make it out. the only issue is that it does not have a locking diff.

    If you find 7.50R16 tires for the back you will have even more traction in the snow. The tires are narrow and cut through to the asphalt. The 235 tires are a little wide you end up with not enough space between the tires. There is no place for the snow to go. The back tires don't act as individual tires.

    You mount 7.50R16s you will have 2 inches between tires right now you have 1/2 inch between the sidewalls.

    dauly rears start to act like "snow shoes" if you don't have enough gap between the tires. When I worked at TGLC most of our trucks were 2wd f450's with a mini spreader on the back and 1-2 pallets of ice melt. Worked fine....

    The old F-Superduty (450) and the current F-450/550 have lots of space between the tires. The F-Superduty trucks use wheels with deeper offset so they still run a 16 inch tire like a F-350 but you can run a 235 tire and have lots of space between the tires.

    A F-350 Chevy 3500 or or a Dodge dually using 235/85R16 tires don't quite have enough space between the tires. I used to run 235s on Ford 350 duallys but you don't have much clearance between the sidewalls.

    On Chevys it is a little worse same with newer Dodges.

    The 7.50R16 is a inch narrower than a 235 so that gives you almost 2 inches between the duals.

    i know winter tires should be narrow, but i couldnt find a 215 or 225 width tire in a decent height with load range E and good traction which is why i had to step up the 235 bfgs.

    the stock 225/65/r16 tires were just a joke.

    The 7.50R16 tires are 32 inches tall they only come in 8ply or 14ply.

    The 225 tires are a joke and the 215s don't carry any weight.

    I like that truck called "snow slayer" thats good! There is a guy around here that uses a older Chevy 3500, but it is am HD model, I think it is an 1992 or 93? I used to think the 3500 and the 3500 HD were pretty much the same thing except for heavier springs and little things like that, but I was way wrong! The HD model is closer to a 1.5 ton than a one ton. I noticed it has the 19.5 wheels, and also the solid front axle, but no 4WD available on the HD model, at least on that year. That is odd? I believe it also has a much stouter rear diff. too. They are heavy duty trucks, much heavier than any one tons! I do not think they make the Chevy 3500 HD anymore though, at least not like the 1992 models anyway! BTW, it never had any trouble plowing snow, I guess because it is so damn heavy?

    Gene if you went with 7.50R16 tires on the rear and 235/85R16 on the front it would be the best combination.

    The 7.50R16 are 14ply they have a load rating of 3100lbs each a 215/85R16 10 ply is only 2400lb load rating a 235 has 2700lb load rating.

    The 7.50R16 14 ply were a very common tire around here before you could get 19.5 tires. The 7.50R16s would cause the wheel to bend or deform before the tire gave out. Very tough tires getting hard to find now.

    Bridgstone V-Steel VSX was a common drive tire the loggers used to buy them.
