- Hey guys, Shawn again, Custom Offsets,
Custom Offsets TV on the YouTube.
Got another I Never Knew sync video for you.
If you remember, this series is
when we come across something we're like,
wow, that kinda caught us off guard,
or wow, we forgot we that we knew that
and kinda have never really talked about it out loud.
That's when we decided to share this stuff.
So we're sitting here building this sweet
high country 2500HD Duramax bad-a**ery
and these are his new 22 by 10 American forces wheels.
And he went with one of the strongest tires we know of
on the market right now which is the Nitto Ridge Grappler.
And it had these sweet not-so-cool-looking
Wrangler highway tire things with these sweet chrome wheels.
And here's something that caught our eye
that we just wanted to share with you guys.
And the name of this episode is,
"You Better Start to Give and F About Your Load".
Load index, load index, load index.
We've talked about this a couple times
and it still is something that, you know,
we have to pay close attention to here at the shop.
This tire has a load index, this is the factory tire
off of this brand new truck, of 121 over 118S.
So it's 121 when used as a dually, one two one, 121.
And it's a 118 when used as a single.
So it's got 118 load index.
What that means is when you get new tires,
you're gonna want to match them up
at the same number or higher or you start to relieve,
lower, you start to lower the load index of the vehicle,
the amount that it can handle.
So basically this becomes your weakest link on the truck.
This is a Nitto Ridge Grappler.
It's a new tire that came out.
It is a 12-ply rated, F load,
high-bred, on or off-road tire.
So this must be the strongest tire in the world.
This is load F, not load E.
Like everybody says, hey, it's load E,
I can put that on my HD or Super Duty.
This is even stronger than that, it's a load F.
So this must be rated, right?
This is a 114 index.
So if I look at the sidewall here,
I'm gonna find a 114Q.
That 114 is the load index.
What that means is if you go out on Google
and you just look up load index chart, I happen to have mine
saved on my camera so I can look at it anytime.
I can see that the 118 that this truck came with
and that it prefers you stick with
is 2910 pounds of load-carrying capacity on this tire.
So 29 10, 2910.
This 114 is only 2600 pounds, it's 2601.
So right there, going from this load E to this load F
which is supposed to be a higher rating,
the load index though is lower.
And the biggest reason for that, if you look at this,
this I'm sure is a 20, let me look at it.
It's a 20-inch wheel so you have all this sidewall.
Sidewall equals load-carrying capacity.
You have all of that air
and all this tire technology that makes that happen.
This one you're starting to shorten up that sidewall
to about a quarter inch sidewall because it's a 22.
Because it's a 22, it takes this load F 12-ply rated tire
and it drastically reduces that load rating
and brings it down to that 114.
So now if you run that 114 on this truck
which he's going to, he understands it,
this is exactly what he wants,
this is what the customer's requesting, he knows
he's dropping his load index by about 300 pounds or 10%.
Now that truck is rated to be towing around
skid steers and fifth wheels and all that stuff.
He's not doing that with that truck.
He's gonna use it for some light towing
and some Duramax-type stuff.
But it is not a work truck by any means for him
so he is totally comfortable with this 114
and being around that 2600 pound load index.
So we just wanted to share with you,
we started to gain the impression, oh, it's a load F,
throw down all the Super Duties, throw down all of the HDs,
it's gonna be perfect
for every single heavy duty application
and didn't even really think about
you still have to consider that three-digit number
and look up that weight rating
and make sure it's a bigger number
than what you have with your stock
or what's on the door if you open up the door.
That sticker inside the doorjamb there
will sometimes give you that load rating.
We never would have thought that that load F
would be rated less than this load E
just because of the size of the opening inside of that tire
but that's exactly the case
and that's all I have to know about that
and that's all you should know about that.
