    sorry to add to past threads.

    half ton chevy. 7.5 fisher. 500 lbs. ballast. bfg at's rated up to 80psi.
    running front at 60lbs. back at 55lbs.

    tread on paper test (laid paper down drove over it). with plow on front and ballast in front tires fully track. back not full out to edges and does not fully track..
    with plow off. front ALMOST fully tracks but not quite. Back still does not fully track.

    possible things that may be added to truck on off and on basis. ten horse snowblower. two hundred lbs. of sand/salt. but these wont be in most of the time obviously.

    so am i good? i put way to much thought into this i think and still ended up with no answer since the amount in the back of the truck will change anyway other than the permanent five hundred lbs. in concrete blocks (snowblower, salt sand, snow). I am considering bringing the front down to 55 and the back down to 50lbs. Or the front to down 50 and back down to 45. appreciate comments/suggestions..

    im not a perfectionist or anything honest.lol

    i dont want to frig with the tire pressure all winter. just once. and done until spring. you actually change your tire pressure everytime you put something in a truck or put your plow on?

    i actually never even thought about tire pressure until i read a old thread on here saying to increase the pressure in the winter time when plowing or holding ballast.
    now that i read it i want it right.... even though i never even thought of it before.

    any off-roader and me will tell you to run the LOWEST presure poss. (more traction)

    the tire says for exmple: max load 2167lb at max infl 80 psi. so the only time you need 80psi is if you are putting 4334lb on the front axle. POINT BLANK. you can check this at any grain elevator or weight scale of any sort but just remember to weigh 1 axle at a time

    my 01 chev 3500hd cab/chassis with a besler hydraulic hay bed, a cattle BUMPER(not cattle guard) and milemarker winch with 2two big round hay bales on the bed has 4200lb on the front axle, and it has a duramax w/ auto and 4X4, the entire truck loaded weighs about 12000lb

    edit: P.S. back off on the tire rating next time you buy tires i guarantee you that your truck does not have a 4334lb front axle, this will help with ride tremidously, just because it's a truck it doesen't mean it's a one ton

    I agree, for off road lower your psi for traction.

    But ;)
    To help avoid busting a bead loose when running over curbs or running over unseen landscape and your loaded down with over 1k some times 2k+ of weight.
    Run the psi up.

    dude i am sure you know about plow stakes right:confused:

    run it up to 90 or 100psi heck it aint my backLOL

    we have a halve ton 4X4 std cab long bed with a meyer 7'6" and NO NO NO NO NO NO NO ballast and does fine even in the 24" thunder snow (wet stuff) :rolleyes: maybe i ought to blow the tires up and put weight in it to reach the same affect? idonno LOL

    I'm not sure what your bragging about?
    I din't even know it snowed on KC,MO!

    Try leaving the air in'um and add some weight behind the wheel wells.
    This will help with handling and traction.
    ( unless you like running around with your but in the air?)

    P.S. what the he!! is LOP0A:salute:

    NO SNOW IN KC. whats wrong with you man? we get upwards of 8-10" avg year.

    i guess what your saying is the heavier the truck the better fuel economy:confused:

    i guess we here at 822ft get the good wet stuff and by the time it gets to 1436ft the only thing that is left is the light fluffy stuff a kid can shovel

    LOPOA: all you have to do to join is send mark o a donation LOL i think it goes to some sort of "get LLM high speed fund"?

    You should fill your tires to whatever the manufacturer recomends, just look on the door jam. My GMC is 65/80 front/rear i believe.

    You never want a wider footprint in the snow. You want a skinnier footprint to go through it, not a wide footprint to go over it. That's why every snow tire ever invented is skinnier in size.

    What if the door jam calls for 80psi but the tire says 65psi max are you going to fill it up to 80psi:confused:

    IE; stock, your truck came with load range "E" tires
    but your using load range "D"

    Yes some load range "D" can have the same capacity as some "E"

    Next, You can get any tire with a M/S stamp on it even wide ones.

    285 bfg,at/to's load range "D", Max load 3305 lbs,
    I run 62 rear & 64 front.

    65psi is the max tire psi, yet the door jam says 65 front & 80psi rear.
    You would have be crazy to put 80psi in that tire but that's what the door jam says..

    I don't think it's legal for someone to put tires on that don't meet the minimum OEM standards. And obviously if you start using tires that aren't recommended, you can pretty much negate the recommendations for tires at that point.

    I wasn't talking about Mud + Snow tires being wide, i was talking about Snow tires being wide. The same principal applies to every car on the road - not just trucks.

    I never said you couldn't find a wide snow tire.... it wasn't a dare or anything. I was just pointing out how they're designed.
