Load range C vs D vs E

[jadmt]

IMO the friction of a 35" MT might put more stress on your Jeep than a 37" AT, even though there is a slight difference in the weight. I could be wrong.

I have had both at’s and mt’s in moab and strangely enough with at’s several times i got the steering hot warning and that never happened with the mt’s on same trails and similar temps. I can’t explain it.

Interesting. I've done it with both, but I don't know that it was really more frequent with my Trail Grapps, and that was aired down to 10 psi. Didn't happen our day in Moab since it was cooler, but threw it several times on the Rubicon with 80+ temps. In high temps that's pretty much as common as it was on the 37" KO2s in Moab.

I was referring more to the friction of turning a tire on pavement. The MTs being softer rubber seem like they would cause more friction than the AT. That said, maybe a MT has less surface area so it balances out.

Sounds like the load D Baja boss MT’s are a good tire … 35…agressive, lighter(ish), and from what I’m seeing about 45,000 miles out of a set with 5 tire rotation. … this sounds like a pretty good deal. Of course they are expensive as all get out! The AT’s appear to be about $120 less on discount tire but only about 10k more miles.

I had over 70k miles on my BBAT’s before they were close to the wear bars.

I am running Cooper load range E on my 2 door because they were cheap AF and it’s a budget build. They are extremely smooth and quiet running on perfect pavement but I feel like ace ventura getting jolted around on everything else. Will get a lower rating tire next time.
it was a trade-off I expected.

Here is what I am doing. (Loade range C) 75.7 pounds.

Nope. This is a common misconception. E-rated tires do not automatically have "thicker" sidewalls. If you actually look at the construction of different E-rated tires you will find that sidewall thickness and construction varies greatly. Furthermore, "thick" sidewalls do not equal "strong" sidewalls. As mentioned, the 10-ply sidewalls on Duratracs are weaker than many 5-ply sidewalls. This is due to advancement in material technology. Newer C-range tires are tougher than many old E-range tires.

Don't get me wrong, you may have had C-range tires in the past with "weak" sidewalls. The point is that you can't judge how "tough" a tire is by its load range. Load range is for carrying capacity and is achieved through many different methods that vary by manufacturer.

Just an FYI.....there are no 10-ply or even 5-ply sidewalls. Those numbers are ply ratings, not actual ply numbers. The vast majority of off-road tires have 3 plies, a few of the hardcore tires have 4.

as long as they're not sagging.
i hate saggy tires.

C or D is what I prefer. Both tire load range and bra size.

 

[zouch]

do you mean the feeling when you're driving?

i'm not surprised, because the KM3s i'm running now feel nowhere near as nice the the Mickey M/Ts i was running before. Mickey seems to have a ride i prefer.

You'd be shocked at how light my 37" Mickey Thompson BBATs Ds feel in comparison to the same spec (but smaller) KO2s. I wasn't expecting that...at all.

i'd be more concerned about the change in radius than the weight.
weight is a factor in ride, and to a lesser extent in acceleration and braking, but it's of much less significance in drive ratio than changing tire diameter.

What are you geared at? I was going to run the ko2 at a C because it’s light and I’m undergeared

Yes that is why I was thinking I could sneak by with the smaller ko2’s but I’m rethinking that..thinking those Mikey MT’s in a 35 sounds pretty good. Meaty tire in a D load range and a little lighter than my falkins.

Great tires.

Yes this is another great point that I forgot about - the ply "number" isn't even an accurate number. Then there's the matter of what exactly the plies are made out of and how thick they are.

To the person that was certain you need a load range E, or at least a load range D tire for it to survive offroad, I don't think that is the case at all. When a tire manufacturer makes a 33" or 35" tire, what do you think they are making it for. I would think most of the people that buy those tires buy them for street use, with a few that buy them for offroad. When that same manufacturer makes a 40" or 42" tire, what do you think they are making that tire size for. I would think that almost every single person that is buying a 40" or 42" tire is buying them for offroad, but still a few buy them for street use.

Then look at the Toyo MT for example. 33" and 35" Toyo MTs are only available in load range E. 40" and 42" Toyo MTs are only available in load range C. So why would they build a tire size that is almost exclusively used for offroad in a load range rating that "won't survive offroad?" They wouldn't. A load range C Toyo MT is one tough tire. I've been using Toyo MTs for at least the last 20 years on numerous different vehicles, and I've never had a flat with a Toyo MT. I've had numerous flats with both BFG and Goodyear tires, the two weakest tires in the industry if you ask me.

Go check out Ford's advertising and marketing for the Bronco Sasquatch.

They constantly pitch the MT tires and go as far as to call them mud terrains as well.

"STANDARD 35 INCH MUD TERRAINS"

The Goodyear Territory's MT stands for Maximum Traction, which I totally agree is very misleading to the consumer and shouldn't be done.

Discount says they're mud terrains. Tire Rack says they're all terrains.

They visually look like an A/T to me.
