F Load (12 Ply) rated tires

Are they really that bad for the 2.5 Gen Tundra? I've seen references about weight but looking at manufacturers specs, a F load tire isn't much heavier. In some cases, there are F rated tires from one manufacturer on par with E rated tires of others.

I've read the stiff side walls translate to a rougher ride as well.

Do these need to be run at higher pressures?

The max load my truck will see is a camp gear load plus some bikes.

 

It will ride rougher, how much would depend on many, many factors like what you had before, psi, weight, load. I for one am a huge fan of overkill tires. That philosophy has resulted in me never, ever getting any tire issues such as punctures or any other tire damage over 5 vehicles and 10+ sets of tires.

 

There is no upside. There are better options no matter what you’re trying to achieve.

And I agree with having tires rated above your use but what are the F load rated for? 5,000lb/tire?!?

 

stick with e load which is way beyond what the tundra needs. I run e load, stiffer for sure. Would not even consider running F load on a 1/2 ton

 

I also run E but would be happy to go down to C if I could find them in a flavor and size I like. C rated is still overkill for our trucks but that’s how I like it…

 

OP are you planning on pulling the space shuttle?

 

I see how the increased ply's make them stiffer but how stiff...like a car on cut springs?

Can it be mitigated with compression settings on your dampers?

From what I can tell, the common sizes run on a custom 2.5 Gens are generally overkill to begin with.

 

If I win that contract, sure.

 

But really, the point being made about what you're pulling with your truck can be made about a lot of other mods. In some cases, mods are done for personal taste and not function. Maybe a product checks all the boxes but 1, and you're considering the trade-off.

 

I'm saying, what's the drawback to running F load when not warranted? I've seen the weight argument. Stiffness, can that be quantified somehow? What else? Does the tire turn square if running a light load?

 

What purpose will it serve? I wouldn’t do it.

 

I run 12ply/F rated 35" tires, only cause the Milestar only makes them F rated for my 18" wheels at that size, and fill them to 33-34psi. They're not that bad honestly but you can notice a difference in ride comfort.
If you're looking to get the most comfort then I honestly wouldn't run them, just stick to 8ply or 10ply. If you don't really care too much, I'd say go for it, especially if the price is better than other options.

 

Aside from weight and stiffness, cost and easy of locating tires when your in a pinch would be other drawbacks. You are essentially asking us, i know about drawbacks, but what are the drawbacks......it wont blow your truck up.

 

In terms of ride comfort, does it make you dodge stuff cause it’s too jarring. Jokingly, would I need a chiropractor and use a mouthpiece while driving?

I have E loads on my 4Runner riding on Kings. They felt stiff initially but I had my compression settings closer to closed. The stiffness went away after backing off on the compression settings.

 

Lol nah, it's not that bad, yea my suspension plays a part of it but I don't dodge anything, couldn't even if I wanted to. I'm in a refinery town, a lot of the roads out here are crap; holes, cracks, bumps, chunks gone or almost no road left.
