Correct. They are "E" rated. Hankook wants me to put them back down to 35 PSI. They feel good there but they look low and my mileage has increased from 19 to 20.5 MPG with them up at 45 PSI.

Regardless of what Hankook says, 35 is too low for a load range "E" tire.

Read my original post and you'll see why I started this up again. I totally agree with you

I'd feel a lot safer running a E rated LT tire at 45 psi as opposed to 35 psi. I always ran 42 to 45 psi on the LT tires I had in the past with no problems. That was for daily driving...any towing or hauling I would add air accordingly.

No need for me to read your original post - but perhaps you may want to review the whole thread from the beginning paying particular attention to kingfish51's posts.

I run 42 psi in my 255/80-17's.

I find this to be a good compromise in ride compliance, payload and wear patterns. The "tech's" at the oil change shack says the tire sidewall reads 80 psi so that is what it is supposed to have in it... TPMS comes on at 35 psi I believe.

I called Discount Tire where I just bought them and the salesman told me that the truck called for 35psi and it doesn't matter what the rating is. This dosen't sound right to me. Any opinions?
my door sticker says 55front 60rear. That doesnít seem unreasonable for a tire that can take 80psi. But thatís just me talkin, itís really up to you...

Your door sticker says 55 front 60 rear because it probably came with load range E tires. If the door sticker says 35 it probably came with standard load tires, most likely P-metric and not LT.

I just yesterday bought a set of Cooper AT3Lt 265/70/17 121s E. The sticker says 245/75/17 121s E with 55front 60rear but Discount put them at 36f 38r. They reset or relearned the tpms but 50í down the drive it showed a low tire. Just put them to 50f 55b to see if light goes off. These tires are ECE certified too. Are all tires ECE and DOT certified now?

Put them at 55 and 60 and relearn the TPMS again.

ECE is the European specification. DOT is the US certification.

Those certs are usually rubbish. Just like UL and EU certs on consumer electronics.

If a company has enough money, they can pay for those labels and built junk products that will burn your house down.

I don't pay any attention to them anymore. If something looks sketchy, I usually pass on it OR I buy it and make it right (add fuses, etc).

Same thing with tires. I do some research even if it's cheap tires. See if folks have issues with the belts or random blowouts.

Wasn't saying Cooper tires are junk.

Cooper tires are great tires.

What I'm referring to are those cert markings.

Most name brands that you have heard of, are safe for the most part.

What I worry about are those low price tires with brand names you've never heard of. Allegedly, the Chinese are flooding the market with cheap tires, and some are not safe.

Yet, I just put a set of low cost tires on my truck. I'm still alive. Didn't get killed yet. But that could still happen.
