Right Tires

Personally...NEVER go "CHEAP" on any safety component...both for 'me'
and my 'family'...

Price to pay in my book

Your rims are *NOT* 265, but 16" by whatever the bead to bead width is
To have a rim width of 265mm (bead to bead) is to a rim width of approx
10.44 inches, which I suspect is NOT OEM, but OEM would be somewhere
in the 6.5" to 7" range in bead to bead width

Speed rating 'K' is under what most 'LT' class tires are rated for. Most
are in the 100MPH range


B - Up to 31 mph
C - Up to 37 mph
D - Up to 40 mph
E - Up to 43 mph
F - Up to 50 mph
G - Up to 56 mph
J - Up to 62 mph
K - Up to 68 mph
L - Up to 75 mph
M - Up to 81 mph
N - Up to 87 mph
P - Up to 94 mph
Q - Up to 100 mph
R - Up to 106 mph
S - Up to 112 mph
T - Up to 118 mph
U - Up to 124 mph
H - Up to 130 mph
V - Up to 149 mph
W - Up to 168 mph
Y - Up to 186 mph
Z - 149 mph and over

Most 'ST' class tires are only rated for a max of 65MPH. Most 'LT'
class are rated for around 100MPH. 'P' class tires can go over 200MPH
and reference the above listing. Not many know that 'most' commercial
tires are only rated max 75MPH (half inch dia's)




The letter load rating is standard for 'LT' class tires. The numeric
load rating is standard for 'P' class tires, but am seeing more 'LT'
class having both ratings...so think the letter load rating might be
on the outs...as too many confuse them...as see folks referring to 'E'
out of context without the tires size...a 'E' in one size has a different
load rating for another sized tire with an 'E' rating

Just referencing a tires section width, without the rest of it's sizing
nomenclature is out of context

That 235 referenced is out of context without the aspect ratio, and
assume 16, as that the tire dia referenced.

Thanks for all the answer, that helped.
To summerize:
I will stick with my 265 tires, since my rims are 265.
I will look for a E rating and load capacity above 120.
With these facts I will try to find a dealer in Albuquerque, where our Rig is in Storage and see what they have...

$200+ for a tire is far better $2000+ for repairing blow out damage to your unit.

Don't over think it. Any E rated tire and most D rated tires will fit the bill for your truck and loads. Assuming a 2k pin weight.
"standard" E load tires are index 121, for 3195lbs capacity single wheel.
So load index of 121 or greater is what you're after.
As far as type, brand, model, that is very subjective.
I typically solve that part by buying my tires used off Craigslist. Haven't paid much over 50% for new or almost new tires for years for any vehicles.

Sorry the standard 235/75-16 E's will like have a max rating of 3,042# the 265/75-16 E's will rate 3,415# if 17" tire the rating drops 220# per tire.

I'll take a D rated 255 over an E rated 235 in tire sizes mentioned. At least from my experience with my two previous sw 3500 GM's. The D rated 265's Cary the same wt as the 235's. Same diameter, bit skinnier, so handling as not always as good. If you have RIM width, go to the wider tire!

I agree. But watch the diameters too. I ran 285/75 D's on my F-250 and they had almost the same load rating of the 265/75 E's. But I could tell I was rolling a taller tire by the earlier downshifts on grades, etc. And that was with a V-10 and 3.73 axle ratio. With a Ford 5.4 I wouldn't advise any tire with a larger diameter than stock. Maybe a 255/60R16?

Right now I have the LT265/75-16 on the truck. The former owner did a lot of stupid thinks to the car, like installing a performance chip (the car runs great now with the chip), so I think the tires are too big too.
I will buy the standard 235 tires.
Since I drive only highways, I will stick with standard highway tires.
The E rating seems to be a fact, but I am not shure about the load index.
The cheaper tires have 116 and the better one 123. Not shure if I spend the extra money on 123, any suggestions on that?
We use the truck and trailer only 2 months per year for vacation, so I will never drive 50K miles, so the lasting of the tires is not important.
I am more concerned about the safety aspect...

265/75R16E was the OEM tire size on my '00 F-250 and the rear GAWR was the sum of the two tire load ratings. I think 235/85R16E was the base tire though. What is indicated on the sticker in your door frame?

Discount Tire has Yokohama Geolander A/T-S in 265/75R16E for $140 each if that's more in your budget. I haven't run the A/T-S, but have had good service with other Yokohama tires.

Just remember the tires carry the lives of your family!

The 265/75-16 E's will have a 231# greater load capacity than the 235's. The larger tires could have been part of an optional camper package.

I would be looking at Michelin LT M/S2+, shop around for the best price, Costco, might be an option.

The VIN sticker on the Drivers door jam will list the minimum size to carry the GVWR of the truck.

Can't find LT only LTX and they are more than $200 a piece, too much for my budget.

They only have a load index of 114 in 265, that is quite low. Shouldn't I shop for a higher load index?

Yes LTX and $200 each is a diecent price! Great wet traction. If you only drive the truck to pull the trailer they are a little spendy. Then again having a truck that you only drive to pull the trailer is spendy also.
My 265/75-16's have a load rating of 3,415# ea. that is 13,660# of tire capacity on a truck with a GVWR of 8,800#.
