2021 F150 Tremor Stock Wheel & Tires

[FaKtor34]

It all depends on your driving and how sharp, I think till you can replace them they'll work fine.

I’m talking about slowly and carefully working my way around getting to hunting spots.

 

[FaKtor34]

They should hold up just fine, it's when you get on the gas a bit and start spinning the tires that causes the rocks to cut tires down, unless you slip sideways into one but then I don't think an E rated tire would help that much. Jmo

 

[FaKtor34]

Let's just say I have put mine thru the ringer a couple of times and they've held up, lots of clay and shale rock, which is notorious for cutting tires down. If your taking your time, you'll be fine.

Will the stock D rated tires hold up against mountain trails filled with sharp rocks and such?

Just really depends. The amount of plies from the load rating doesn't have much to do with the number of plies on the sidewalls. Some have thicker ones than others even at lower load ratings. I've seen sticks through the sidewalls of E rated tires too. I wouldn't really use any AT for a rock crawling tire anyway. I think paying attention is the biggest key.

I've had mine out on some pretty bad rocky roads and they held up just fine.

And keep in mind the stock tires aren't even C, D or E rated....they are SL.

 

[Tremhunter]

That can’t be. I just read SL tires are the lowest rated tires.

 

[FaKtor34]

Sorry but it is the truth, but like I said they've held up fairly well for me so far, if I do cut one down then I'll consider replacing them, if not when they are worn out or I get a coilover leveling kit, I will.

 

[Tremhunter]

Has anyone considered swapping them out at the dealership? Is that even an option?

 

[FaKtor34]

You can ask, some will of course you'll pay the difference.

In my opinion Ford not only did this to save cost, but to help boost the MPG numbers that they advertise on this truck. The OEM tires weigh 46 lbs. The E rated Generals weigh 61 lbs. Running a tire this heavy would result in a noticeable drop in fuel economy and performance too (google rotational inertia). My Tremor will be my daily driver so MPG will be important to me. When I look at replacement tires, I’ll be looking at the tire weight for sure. Don’t get me wrong…I agree that Ford is putting the wrong tires on these trucks.

How many mpg less are we talking? Drop in performance in what regards? I would love to keep it simple in my mind switching SL for E rating.

It'll be up to 2 depending on traffic type

 

[Tremhunter]

The general grabbers are good tires. Extra plies changes the rating to E? Sorry, all this tire talk gives me a headache.

 

[FaKtor34]

Don't worry about them till you have a problem, as I said they have held up to what I've put them through so far. If you do cut it down odds are you would have the E rated tire as well.

 

[FaKtor34]

The difference is the E rated tire has more plies, which can make it more durable but as someone else said earlier, @RotorHead695 , that doesn't necessarily mean it is more durable. What it does mean is it will be more stable while hauling or pulling heavier loads. For 80% of the users here the tires will be fine for most of what they do. I don't plan on swapping till I have an issue or when I get a coilover leveling kit installed, then it will be a larger diameter tire. Wasn't trying to sound ill earlier, just trying to say you probably are worrying for nothing.

I suppose it's about the context of the word durability. "Longer life" can, and in my context is, about not blowing or tearing a sidewall during my use. Basically, the higher the rating the more "layers" (not exactly accurate, today) or the thicker the non-tread portion of the tire is (this can be witnessed by the weight of the tire) this translates to how tough the tire is and what it can withstand.

As faktor34 mentioned, our OEs will be good for 80% or more of us and the ones that need more will know it.

 

[Tremhunter]

I sure don’t want to find out I need more when I’m 10 miles back in . That’s why im on this forum. To learn.

Just had some Mickey Thompson 305/70R18 installed. Tire guy said they wouldn't fit. They did. Now I'm trying to decide what offset of wheel I can fit....the math here hurts my brain.

Have your tire guy add spacers until you get to your offset then start looking for wheels
