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.

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?

You are correct on size! Tall and narrow. Maybe these just like more psi than the duratrac for towing. Will try.

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.
