I have a 2013 XLT with a 1400lb. payload and am currently running Falken Wildpeak AT3 275/65/18's which are an E rated 10 ply tire. I don't do a lot of hauling but I do pull a lightweight TT which is 3400lbs. using a weight distribution hitch. These tires are fairly heavy at 6olbs each so I am considering the Wildpeaks in a XL 6ply or a SL 4 ply as I don't think I really need a 3400lb payload tire? Any opinions or info apprecaited here?

You don't NEED an "E" rated tire. A "P" rated tire is good for more weight than your truck is rated for. But other than costs there isn't much downside. You can experiment with different tire pressures and get about the same ride and fuel mileage with any of them. I currently have "E" tires on a Tacoma and with the right air pressure the ride is the same as before and there was no loss of fuel mileage compared to the older "P" series tires on it. My F-150 has "P" rated tires because that is what was on it. I'll be going to "E" rated tires next time. I don't need them for the payload, but they are a tougher tire for off road driving and the extra strength is worth the cost to me.

Most people don't use 10, 6, or 4 ply to describe tires anymore. Instead most refer to them as "P" rated or LT tires in "C","D", or E rating. A "P" series tire is rated for the same payload as an LT tire in a "D" rating. Going to a "C" rated tire in an LT would be a lighter duty tire than the "P"s that came from the factory. The "C" rated, or 4 ply tires are meant for lightweight SUV's like Jeep Wranglers instead of trucks.

If I weren't going to stay with "E" rated tires I'd save some money and buy "P" series.

Yeah, the E is more than you'll need. The payload of them is probably higher than that of your wheels.

the HDPP trucks come with C rated tires.
The only thing the C, D, or E rated tires do for you is possibly reduce Porposiseing (That up and down rolling sensation when towing heavy) Softer sidewall tires (P rated) are part of this. Stiffer side wall (Higher load rating) can help counter this at the cost of unladen ride quality (can be a harsher ride with out a load) . You have to pick your battles. I like the C rated on my HDPP. Good unladen ride quality not bouncing upd and down when loaded.

My 2016 came OEM with Wrangler Fortitude HT 275 65 r18......116T, rated 2756 lbs max at 51 psi.

The Wrangler AT/S in same size LT C, specs out at 2535 lbs max at 50psi.


Which tire is tougher offroad?

Which tire can carry more load?

Puzzled why a 116T tire that weighs about 10 pounds less than the LT C tire is rated for more load.

HDPP trucks 2014 or older came with E rated tires. My 2014 HDPP F150 came with LT245/75R17 LRE tires.

My 2018 Lariat HDPP came with C Rated Tires
Here's the yellow payload sticker NOTE the C Rating

Please note, I specifically mentioned 2014 and earlier in my post. The post I answered just said all HDPP trucks came with LR C tires which isn't exactly accurate. If anyone buys a 2014 or earlier HDPP, they will find the OEM tires were LR E tires.

Ford changed when they went to the aluminum body. Maybe Ford engineers decided LR E tires were overkill and so dropped down to C tires.

the E is nice to have, but not really necessary for what you're doing. LT's would fit your purpose the best

True for 2018-up F-150s. But 2015 through 2017 F-150s with HDPP and XL trim came with LT245/70R17E tires on 6-lug wheels. All F-150s with HDPP before 2015 model year came with LT245/70R17E on 7-lug wheels.

True for XLT and above trim. For XL trim, the 2015 thru 2017 F-150s with HDPP still had load range E tires, but the 17" wheels changed from 7-lug to 6-lug.

Actual number of plies went out back in the 1960s when radial tires began to replace bias-ply tires. Ply rating continued until a few years ago and is now obsolete. Load range "C","D", or E is now obsolete also, replaced by load index. Load index is a number between about 100 and 130, but that's a lot harder to remember than B, C, D or E, so lots of folks still use load range instead of load rating. Here are the load ratings most folks with F-150s might need:
109 = 2271 pounds max tire load
110 = 2337
111 = 2403
112 = 2469
113 = 2540
114 = 2600

And simply saying "P-series" is not descriptive enough, because there are standard load (SL) and extra load (XL) P-series tires. You probably have to look at the load rating to tell the difference. My P-series SL tires have load rating of 110, but some P-series XL tires have load rating of 112 to as high as 114.

The stock-size tires on my F-150 have load rating of 110, or max load of 2,337 @ 35 PSI or more. That's enough weight capacity for GAWR of 4,674 pounds. 2012 HDPP F-150s had rGAWR of 4,800 pounds, so they would need load index 111 or higher. So what did Ford install on an F-150 XL with HDPP?
