I am really enjoying mine. 38x12.5R17
Just got home from a 36 mile trip and they were a delight. 😂
They are a lot smoother riding than the 38x13.5R20 STT Pros they replaced, but a sidewall will do that.
Here's a side by side shot but keep in mind the Grap is not mounted and has no weight on it.

They are quieter, but they are a different frequency and it almost matches the sound of the engine revving and makes me feel like the trans isn't shifting on time, just by sound. Of course it is shifting correctly and with the tazer the speedo is dead on with GPS. It just takes some getting used to. I'm used to the deep growl of the more aggressive tread and this one makes me think something is not right.
Just my own issues probably from driving clunkers my whole life and having to worry about a break down constantly.
The auto stop/start used to give me a minor heart attack at every stop light cause I'm so used to my old POSs stalling on me when I'd come to a stop. Lol, bypassed that option immediately. The old ticker couldn't take it anymore. 😂

I can understand that.

I can understand that. Ive ran the coopers in the past and they’re not atrocious but you definitely feel the lugs at slow speed and hear it at higher speeds.

I think they're perfect.
Those look great!

Are those Methods the 8.5” or 9” wide version? I’d love to run these tires to save some rolling resistance but not sure if my 9” beadlocks are too wide.

The Nitto specs for 11.50s are shown measured on a ( 9" ) wheel

They are the 8.5" but check Nitto's website for wheel width range, I don't think they'd be too wide. A 1/4" extra per side. Tires are only 75 lbs, can't beat that.

After usage, do you feel like the 11.5 width is a hindrance here in the southeast? I'm worried about our deep mud and it just digging more than my current 37x12.5 and finding no hard bottom.
Doesn't help my feelings with that being I'd also be coming from a Cooper STT Pro to a Toyo RT Pro. I get its an aggressive RT but it's still obviously not on the same level as the STT in terms of mud performance.

Appreciate any insight!

That Toyo RT Pro is pretty aggressive for an RT, kind of wish those were out more before I got these. I have a buddy that runs the STT's and swears by them. I haven't had an issue so far but I bet when they get more miles on them there will be a drop off in performance. Those Toyos look like they'll be fine over time. The 11.5 v 12.5 is a whole nother conversation that everyone has opinions about. I air down to 10-12 which gets me a nice contact patch. I just like the lighter stearing in the 11.5 and the weight savings. I'll keep the best one as a spare and get the Toyos in the same size next time. Post pics when you get them.
