should I air down more?

Thanks, Im pulling to the right some even after alignment so I'm hoping airing down a bit more might correct it but idk I doubt it will.

The Patagonia isn't a square pattern tire. The tread is supposed to be crowned. I wouldn't go below 30psi on a tire that small.

I took it to 30 and we will see. Doing some interstate driving tomorrow hopefully it acts good.

Hope all you want, but airing down won't have a significant impact on it pulling in one direction or the other.

Yeah I didn't think it would but won't have time to go back to the alignment shop to have them try again for a week or so. Although it is better than it was before the alignment. Hoping it's not the the tire that is causing it. I should've probably swapped the fronts today to see.

When i had stock tires (ko2), I had them at 28 psi.
Im now on 38s and at 26 psi.

Alignments are like a box of candy. You never know what you are going to get.
4 years ago I took my jeep to three different shops on the same day and all the print out where different. One said I needed caster camber bushings and they don't do that. another said something different. I finely took it to my local 4x4 shop and was told all was fine just needed a toe adjustment. I also found out over the years that both my 4x4 shop and Metalcloak recommend toe at 0 or out 1/16th. I resisted but finely set my toe to 1/16 out and it almost eliminated my shimmy when hitting bumps at speed.
I now align my jeep with an angel gauge and tape measure.
I run 26psi cold on my Rubicon with 35s and 24psi cold on my Willys with new 38s put think that the 38s are still riding to much on the crown of the tires. More testing.

New tires unfortunately load range E they are Patagonia xt 285/75/17. This is what it looks like when it gets wet pulling into a car wash bay. I don't have chalk to test that way.

Should I air down more? I'm sitting at 34 psi cold these were probably at 36 in the car wash or 35psi.

Why in the world would you buy an E rated tire that small? That thing must ride like a brick. You could probably air down to 2 psi and that thing would still be stiff. Like others said you bought Pats and they are a crowned tire meaning they are not designed to run with the entire width touching the road like a Nitto Trail Grappler for example. You are pretty much stuck at 30 psi IMO. I'd throw those tires in the trash and get something else. There are plenty of options with a C sidewall in that size.

Just took a long drive on them yesterday and it didn't seem much worse over bumps and crappy roads than the OEM tires those Firestone destinations sucked. I ran 30 psi cold and they got up to 33psi maybe 34 for a min on a couple hundred mile drive. I will go with C next time but these were a pretty good price in comparison saved about $500 to $600 total compared to the Toyo open country
