This TRA pressure chart from Toyo tires...down on page #A8 shows a P265/65-18 load numbers.

Remember a P tire on a truck or trailer is required to have its load rating decreased by dividing that number by 1.1....in other words the 2469 lb rated P265/65-18" may now have a 2244 lb capacity

??? :h

Never heard that one before. Can you show us a reference? Is this assuming that the load sticker on the truck specifies LT? If it is, I can tell you that most 1500/150 series trucks and large SUVs come with "P rated tires, and their door stickers reflect that.

The tire placard specifies the tire size and recommended inflation along with GAWR. I have never seen a placard with a stated vehicle load other than GAWR.

As you can see from other posts the "De-Rating" is industry standard and the DOT regulations follow those standards. If you apply a "P" type tire on a multi-purpose vehicle (SUV or Pickup) or on a trailer the load capacity seen in the Load Inflation tables must be reduced by dividing by 1.10.

Its a fed requirement per tire selection CFR 49 571.110/.120

571.110 for 10k and under (snipped)
S4.2.2.2 When passenger car tires are installed on an MPV, truck, bus, or trailer, each tire's load rating is reduced by dividing it by 1.10 before determining, under S4.2.2.1, the sum of the maximum load ratings of the tires fitted to an axle.

And for over 10k vehicles;
571.120
S5.1.2 (snipped)
When a passenger car tire is installed on a multipurpose passenger vehicle, truck, bus, or trailer, the tire's load rating shall be reduced by dividing by 1.10 before calculating the sum (i.e., the sum of the load ratings of the tires on each axle, when the tires' load carrying capacity at the recommended tire cold inflation pressure is reduced by dividing by 1.10, must be appropriate for the GAWR).

Open the door and you will find what is recomended for inflation, then look on sidewall and see what max pressure is. After that adjust til your happy.

Checked my web photo hosting and find that there are a few others
showing under PSI shredded...posting here along with my cryptic
search verbiage...so that I won't have to open my photo host site...



Yes...this also a very low profile and have no idea what it's
aspect ratio is...this is all that was left at the curb side

shreddedtire shredded
underPSI underinflated toolowPSI















This one is of a LT and closer to 65...but still don't know what aspect
ratio it is...cycling at nite and saw this and took pictures. Guessing
aspect ratio of 75 or so...

Sorry...that is the only shredded low profile tire pictures I have...guess to
appease some folks...will just have to keep an eye out for one shredded of a
bit higher profile... :R

Sasha was about 8 years old in those pics...guess he might be over
20 years old or more when I get the next chance to take pics of a
shredded 65 aspect ratio tire... :B


Thought everyone would be able to make the association of what can
happen when the PSI is too low...but goes back to the old adage
that assumptions are dangerous... :S
