Can't wait to get my 37x13.5-18 wheels and STT Pro tires on! The wheels are LRG 106 18x9, 0 offset, 5" backspace. While I can not actually review them yet, they look so freaking awesome that unless they blow goats, I'll love them! $1700 for all 5 tires mounted with Dynabeads. <img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=642825"/> <img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=642826"/> <img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=642827"/> <img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=642828"/>

I got them at a local mom and pop tire dealer. I asked for the best price mounted and balanced, no receipt and paid in cash with no tax or record of sale. It was $1700.
I dropped the wheels and TPMS sensors off (around $45 from Amazon for all 5 sensors) and picked them up a few days later with Dynabeads and all mounted up and I handed him 17 $100 bills. We shook hands and I left with them in my truck.

I've been running 37 STT Pros for a few months now and love'em. Quiet on the road, pull went away when I got rid of the Toyos, had no issues with the STT Pros during our snow storms here in UT, and so far nothing negative about them on the trails.

I've put a few hundred miles on these now, so I figured I'd share my 2 cents.
First off, these are SILENT compared to every other tire I've run on this rig. The interlocking tread lugs do wonders keeping the noise down.
All 5 balanced using very little weight, and ride great at 27 psi. If you are familiar with the troubles I experienced with my MTR's, you'll know how important this is to me.
Offroad, the wider foot print floats over the sand, and the softer compound seemed to hook up very well in the rocks. Went out and wheeled for a few hours, and drove home without so much as a wobble. Overall, I could not be happier with these tires.
Also doesn't hurt that I picked up these 37x13.5 for $303 a pop..

So now there is a thousand miles on the STT Pro tires that I got a couple months ago. 10 hours of 60 mph interstate, and 2 days of Rausch Creek rocks and mud. The tires work exceptionally well overall.
I aired them down to 14 PSI. While I could go lower, 14 psi allowed them to soak up a great deal of the rocky terrain and conform well to the surfaces. The tires stuck very well to the rock allowing me to climb walls with little wheel spin, normally you get a bit of wet/sandy-tired wheel spin and once you get the tread cleaned they grip and pull. The center section does hold onto thick clay at low speed, but the outer and inner row clean out even at walking speed and the tires keep pulling you.
On the interstate at 60, you hear the wind noise over the tires. At slower speeds (around 35-40) you get a soft and constant hum, but nothing radical or overbearing.
They track straight, ride very nice with 26 PSI (37x13.5-18) and down excessively follow road imperfections. You can comfortably drive at 60-65 MPH with one hand lazily on the steering wheel. It actually doesn't feel much different from the factory 32x10 Rubicon/Willys MT.
For use at Rausch Creek or similar rocky terrain, I would highly recommend these tires. They will comfortably make the 5 hour commute to the park, they will let you crawl and climb all over the park and get you back home with no unneeded drama. And they look awesome while doing it all!

What does everyone think is going to happen once the tires wear down to the level of the mud dimples and scoops? Seems like they might be a good idea when the tire is new, but will lose traction when the dimples and scoops become exposed.
