Thank you for your response.

I have looked on Goodyear's website as well as Discount Tire's website, and there isn't a Load Curve diagram. I have also searched the interwebs with no luck..

I understand that I could go through the work of the chalk test, but it is imprecise and not needed when the tire manufacture should have already done this.

I am hoping @discountTire can provide this..

polarisn1 Can you share with me the load curve for these tires?
My understanding is that tire manufacturers create a chart that outlines weight vs corresponding psi that should be ran in the tire.
I'm not driving around with 80psi in my rear tires unloaded like GMC puts on the placard, it's not a good idea.
I just bought 285/70R17 in the load range E category. I love them, but want to set tire pressures correctly for long wear, comfort and safety based on Goodyear's testing, not GM's maximums.
Thank you.

With 15 years in the industry I'm getting pretty good at calling tire sizes by eye

Your Ultra Terrain tires have a max air capacity of 80 PSI cold - bumping the pressure up to max capacity should make a significant difference with how the tires handle while towing/under load.

On a side note, what is the GVWR of the trailer? 1000 lb tongue weight seems on the high side which may be causing some of the squirm you're experiencing.

Discount Tire Hi, ColoradoOutdoors!

I think the pressure may be causing some the the "squirm" that you're describing.

What size UltraTerrain Tires are you running? From your picture I'd say LT275/65R-20?
04-17-2019 07:09 PM
ColoradoOutdoors As I move from ski trips to camping trips, these tires are less in their element. Compared to the Duras and the stock Wranglers, they feel like they are on tip toes. A surprising amount of squirm. They remain quiet generally but you can hear them being pushed at highway speed corners. Not really confidence inspiring. 60 psi, 1,000 pound tongue weight w/ my Lance 2185 TT.

Icutmetl Any more feedback on these? Wonder how the sidewall strength compares to a Duratrac, Adventure, KO2, Falken and similar tires. Also, do they have full depth siping?

novaman64 LOL... I thought that was a while ago, since then I believe they got bought by Sumitomo so them and Falken are the same family. Not sure what their gun logic is now...

Anyhow, its a great tire. Hopefully it lasts, if not, I will look at the Falked Wildpeak AT3W since it looks to be pretty dang close but has a 55k warranty.
