Received my 2022 F350 yesterday (yea!) but was surprised with 6800lb rear axle capacity. Digging further I believe this was because I accepted the standard LT275/65r18 tires which have load rating of 3415lb each (my fault).
I’m considering replacing them with LT275/70r18s that have load rating of 3640lb each. Has anyone received an F350 with LT275/70r18s, and is your rear axle capacity 7200lbs like I suspect?
Additionally, any comments on the value of replacing these? The tire guy I talked thought it was a waste of money. Given my load is in this range I’m thinking even the 200lb improvement per tire might be worthwhile margin.
Not looking for generic ‘weight police’ comments, but appreciate any counsel.
Thanks

Congrats on your new Super Duty. All SRW F350s have the same axles so nothing to worry about there. Also for a 200lb margin in tires I would run the factory Michelins.

FishOnOne - thanks for your comment. I was also surprised that it came with Continentals not Michelin’s. I have lots of good experience with Michelin’s but not any with Continental’s, but the tire guy I talked with had high praise for the Continentals.

A pretty certain bet, is that the OE tires (unless things have changed) are generally the cheapest tires you can find. Notice I didn’t say weakest, as with very few exceptions, a particular size and class of tire is rated exactly the same regardless of brand or model/tread.
If you’ll sleep better knowing you have heavier tires, spend the money, but go ahead and get 285-75s for 4000lb capacity.
You’ll lose money even selling the new takeoffs. New tires will cost you about double of what they’re worth.
Regarding running the tires you have at max load or even a bit over, that doesn’t bother me one bit. Have done it many times, many trucks, many miles. Hell, I’ve pumped up P rated tires to 55-60 psi to stiffen them up when towing more than one should with a half ton on little OE cheapo tires.
I would t go out of my way to buy cheaper lighter tires, but I look at it this way, and many will argue. Tires (rims, anything that keeps a truck rolling rubber side down) have to have a significantly large factor of safety. (Again those in the know will tell you they are only rated to full stated capacity blah blah blah). But the liability is HUGE for mfgs for vehicles like trucks that are basically bound to be overloaded. Otherwise there would be blow outs busted rims and carnage all over from the masses that overload their trucks regularly. Mfgs don’t need that direct and costly liability, so there is more capacity than published.
Unless I wanted “nicer” tires, I’d run em.

Not that most people likely care, but for me the 70 series look better/carry more, and when off road the taller side wall gives more bounce on rough roads and puts the rims further from the mud or rocks. I ran those 65's for a short period to try them and traded them back for the 70's. If your never off asphalt, it likely would not be worth a couple hundred pounds more capacity.

Congrats on the 2022... IF you tow HEAVY, your tires could be the weak link and I suggest looking into selling them on marketplace and using that to upgrade to either 3750# or 4000# capacity..
Like stated above ( fish) the axles are the same, its the tire capacity...
I am not really familiar with the Vanleigh line, what are the weights of the RV? Will your tires be OVER as is?

If the stock tires are in capacity range of your payload, why bother? Buy new tires when the ones you already paid for wear out.

Apologies for the piggyback question but this seems a good place to ask. If I adhere to the payload door sticker (Combined weight of...should never exceed) do I need to be concerned about any specific axle or tire capacity? In other words, if I don't exceed the payload can I assume the rear axle and tires have enough capacity for the load? Just a general question, no specifics in mind. Thanks.

Hard question to answer with out knowing your payload, depending on what is carried in the TV, there are likely some combinations that it might be possible.
