    I used a set of portable truck axle scales yesterday and did some interesting weighing that may prove or discount your ideas on what axle weights do to your tires and wheels. You may find out how easy it is to overload your factory wheels. This is mainly for your truck wheels. KEEP IN MIND I HAVE NO PASSENGERS & BED IS EMPTY OF FIREWOOD, ECT. MY REAR AXLE WHILE TRAVELING NORMALLY WEIGHTS 7080#S. I will also show how raising and lowering your hitch will or will not effect your RV axle weights. Facts will be at bottom. Scales are in 100# increments.
    WITH 5TH.WHEEL PIN HOOKED UP
    2400#S FRONT AXLE WEIGHT 2650#S REAR AXLE WEIGHT
    TOTAL FRONT AXLE 4800#S TOTAL REAR AXLE 5300#S
    BOTH RV AXLES ON SCALES

    REAR AXLE ON MY 06'DUALLY
    NO LOAD .....1900#S ON OUTSIDE WHEEL
    [​IMG]
    REAR AXLE ON MY DUALLY
    WITH RV LOADED .....3100#S ON OUTSIDE WHEEL
    KEEP IN MIND THAT 06" DUALLY WHEELS ARE RATED AT 2600#S.

    *************************************************
    RV unhooked and sitting on front jacks
    Front jacks lowered 8"s from normal
    Front axle= 2400#s
    Rear axle= 2600#s
    RV unhooked and raised 8"s from normal
    Front right wheel= 2100#s
    Rear right wheel= 2700#s

    HOW MANY OF YOU HAVE TRIED RAISING AND LOWERING YOUR PIN OR HITCH TO TRANSFER LOAD ON RV AXLES. DOES THIS PROVE IT IS NOT WORTH THE EFFORT??.:stir: :stir:
    The next issue is wondering how the crown of highways, parking on curbs with one rear wheel, blocking just the rear outside wheels while parked and everyday traffic of rough roads may effect your wheels.:mad:

    That is correct I do have 4 rear wheels to help spread the load. One of my points was I am running close to the capacity of my truck. I am sure many guys are way over and how easy it is to run up on a curb or run the crown of the road and either one of the tires can become suspended in air for short periods and we can overload that wheel for short times.

    Would a 3000lbs weight rating per tire on a 2500 SRW be enough?

    3195 is what most dodges come with if you have the 265-70-17 tires... 3095 if you have the 245-70-17's. so if you have 3100lbs on a tire just sitting there, then a bump puts more force on a tire. but i am surethis is acceptale. im sure shock loads are calculated into the tires while they are being made...

    this is the prime reason i went to 19.5's on a SRW. if i get a DRW or convert my SRW like i want, then i will be going to 19.5's still. way more comfort.
