Toyo/Nitto putting out "F" 12ply rates offroad tires

Sorry if this is widely known. It was news to me and figured some of you guys are running some serious weight.

Some Nitto Ridge grappler, toyo MT and ATII are being offerd in F 12ply rated models for 18" rims in the 33-35" range. There might be more but the website is kinda hard to glance at everything quickly.

"Today's load range/ply ratings do not count the actual number of body ply layers used to make up the tire's internal structure, but indicate an equivalent strength compared to early bias ply tires. Most radial passenger tires have one or two body plies, and light truck tires, even those with heavy-duty ratings (10-, 12- or 14-ply rated), actually have only two or three fabric plies, or one steel body ply."


People need to stop misinterpreting the load rating, bias ply conversion strength rating, to the actual number of sidewall layers ;)

Thats why we say "rated" not that it physically actually has 12ply. Its like how AMD used to rate the amd64 in Pentium terms i.e. 3200+ even though its actual Ghz was like 2.4.

Sadly not in 16 inch...

Really doubt your be able to find 16" wheels with the load capacity to match such a tire anyhow.



That said, Id love to see the actual specs.

This page

http://www.jegs.com/i/Toyo-Tires/894/351490/10002/-1

Shows a load-F AT2 in 35x12.5 for an 18" wheel, and states the max load at 80PSI is 3970lbs
Id expect a true load-F to have a substantially higher load rating.


The load-E AT2's Im running right now, essentially the same size (285/75R18) have a load rating of 4080lbs @ 80PSI

that F 35 is over 500lbs more than the E

35X12.50R18LT 123R E BSW XT 352710 8.5-10.0-11.0 68 17.0 34.5 12.5 3415 / - 65 / - N/A 602

One of the biggest aspects to these is that they can run at 80psi, where most flotation tires (i.e. 35x12) can only run at 65psi. E1 rating vs. E2. On highway use with heavy loads will probably feel a little more stable with the higher PSI

Uh, yeah...

But as I said, the 285/75R18 load E has a greater load capacity (4080lbs) than the 35x12.5 load F

Beg to differ. Up until these Load Range "F", everything with a section width of 305 for metric sizing, or 12.5" for flotation sized had a max pressure of 65psi (notated as Load Range E2).

If you look at the spec sheets on Toyo's site (MT, RT ATll, etc...), you'll see there are now 2 35x12.5 tires for 18" rims as an example. One with a Load Range E @ 65psi max and these new Load Range F @ 80psi https://www.toyotires.com/tire/pattern/open-country-at-ii-on-off-road-all-terrain-tires

A pretty good write up from Discount Tire https://www.discounttire.com/learn/load-range-load-index

I run the Toyo AT2 also, in 285/75R18. 35" tall (Ok, 34.8") 1" inch skinnier than the typical 35x12.5 and allows 80psi. The tallest tire they had that ran at 80psi and the highest load index.

Your right

I was referring to 18's and missed how the 65PSI rated Load E-s were pushed to the next page. :)


Bottom line, I'm interested in the offerings in Load F, but only if there is a SUBSTANTIAL increase in load capacity.

The exact reason I went for the 285/75R18 AT2 is for the load capacity (4080lbs)


And unless the Load F offering has a better load rating, I really don't see the point.

18's maybe but my 35-12.50-17 AT2's are E-rated 65psi and #3195 rated. I keep them @ 50psi all around and they are like rocks. Very stable strong tire.
If I carried a hardsided camper around I'd go w/18's.

Yeah, referring to the 18's

I also run my AT2s at a much lower pressure. And yes, even at lower pressures they are stiff stiff. :snorkel:
