However. First trip out in the rocks I ran 10 psi and got a nasty cut in my sidewall that was close to being a day ender. I didn't happen to notice until I got home and a few days after.

Pretty sure it was in this spot that I had sliced it. It was my passenger front. I was stuck in this hole and had to grip the passenger side wall to get up.
Uh, we dont make a load E 15".

Finally got to wheel these on my own rig last weekend in Hot Springs

Really, really, really impressed. Stickiest "non sticky- nice street tire" ive ever had. Gripped wet rock really well. 4500lb... 10psi front/ 8psi rear seemed about perfect.

Good info, keep us posted on them, how they wear, sidewall strength etc.

I just bought two sets - 37x13.50x17 and 40x13.50x17 for my Broncos. In the process of doing an axle swap so will get to try the 37s out first. The other Bronco with the 40s will be ready at the end of the year...

The 37 weighs 80 lbs
The 40 weighs 90 lbs

I weighed them on a digital bathroom scale.

Im going to buy the 37x13.50 17's for my truck, it was a toss up between these and the Toys Mt same size.
My brother has the Toyos on his daily driver crew cab same size but I wanted to try something different.

Tried mine at Rausch Creek two weeks ago. I've previously ran Toyo MTs and Nitto TGs. Out of the three, I prefer the STT so far. The grip in wet/rocky situation is incredible. No highway miles yet though.

Nice. How do they squat when aired down? Do the sidewalls seem thin?

Originally aired down to 13 PSI and they barely flexed. Later aired down to 9, and they started working better. They were brand new with 0 KMs on them when I hit the trail that morning. Sidewall seems to be of average thickness for a dual purpose MT tire.

Had the exact same experience with mine (35x12.5r15). Next trip i had to air them back up because i went down to like 5-6 on them because they werent squatting down lol

They are a tad noisier on road than bfgs, but its a damn jeep, helps drown out the other noises. Very pleased with mine offroad, done quite a few things i didn't think id be able to, which got me in a few places a had no business

Good job on 7-up. Pics and vid never show how long and steep that climb really is. Looks like the line is easier now that the old dead snag finally fell over.

Check ebay too. Discount tire sells on there and runs promo codes a lot.

As for the actual size of the 40's, I had a buddy measure a brand new STT pro at street pressure and it came out to 38.5" so apparently they run a little small?

That sucks

Funny though because I've been wanting a tire that size, up until I just sold my Toyota axles and now I want a true 40-42
