Options for Tire/Wheel Upgrade

Well, I am considering upgrading tires/wheels. I currently have 17's with LT245/75R17 rated at 3195 ea. I am sure that I am over with full water and want to be able to carry coolers/generator/chairs/firewood/bikes off the rear Titan extension, placing even more stress on the tires.

Option 1:
Keep the 17's and buy LT275/75R17 tires rated at 3950 lbs. ea. Not gaining any rim capacity, and these tires have a tall sidewall (Nitto Dura Grappler).

Option 2:
Upgrade to 18" wheels/tires and LT265/70R18 tires rated at 3640 lbs. ea. Most wheels are rated same. Net gain 890 lbs.

Option 3:
Vision 19.5's. specs not necessary, overkill.

I said I would never buy 19.5's again, I would just buy a dually, but here I am....don't want to buy a new truck just yet.

Opinions?

    Yes, this is true. I'm almost afraid to. This 830 is heavy, but I love it.

    All these upgrades are what drove me to sell my 2011 830...I had no idea at the time I would miss it so much and buy an even heavier one:S

    Plus I have the 6.2 and 3.73's, not exactly a barn burner...taller tires means reduction in effective gear ratio...even more of a dog:(

    Yikes, 3195 lbs.

    My aluminum wheels that I had were 3400 lbs.....and I couldn't find wheels that gave much more if any.

    The Ford 17" rims are not rated for much more weight than your current tires. I also went with 19.5's. By going to 245/70R19.5 tires, you don't have to inflate them as hard compared to the 225's.

    Just went through this myself. I think I even mentioned it in another of your posts as well. As you know, went 19.5's. Nothing else gave me the capacity and piece of mind. Would I have liked to avoid the 19.5's?Before I owned them...yes. After running them for the last few months....I LOVE THEM. Maybe it is the tall sidewalls that helps or the fact I can run them at 85psi which gives a decent ride as well as carries the weight without having a little 225 at 110 psi...I might hate them then.

    I won't go back...and yes, my next truck will be a dually and most likely a 5500 series truck as I will only carry more weight and larger campers in the future.

    That is my opinion..

    You are not saying what type of rims you have, but #1 looks like the option that will give you a lot without any investment (just new tires)
    Steel rims can take overload, while mag factory rims will take a lot most of the time as well
    Just make sure your rims are not the ones having troubles.
    When I bought my camper with F250, the rims were overloaded by like 20%.
    I made close to 4000 miles on them before buying dually.
